On 24 February 2022, Russia invaded Ukraine in a major escalation of the Russo-Ukrainian War, which had started in 2014. The invasion, the largest and deadliest conflict in Europe since World War II, has caused hundreds of thousands of military casualties and tens of thousands of Ukrainian civilian casualties. As of 2025, Russian troops occupy about 20% of Ukraine. From a population of 41 million, about 8 million Ukrainians had been internally displaced and more than 8.2 million had fled the country by April 2023, creating Europe's largest refugee crisis since World War II.
In late 2021, Russia massed troops near Ukraine's borders and issued demands to the West including a ban on Ukraine ever joining the NATO military alliance. After repeatedly denying having plans to attack Ukraine, on 24 February 2022, Russian president Vladimir Putin announced a "special military operation", saying that it was to support the Russian-backed breakaway republics of Donetsk and Luhansk, whose paramilitary forces had been fighting Ukraine in the war in Donbas since 2014. Putin espoused irredentist and imperialist views challenging Ukraine's legitimacy as a state, baselessly claimed that the Ukrainian government were neo-Nazis committing genocide against the Russian minority in the Donbas, and said that Russia's goal was to "demilitarise and denazify" Ukraine. Russian air strikes and a ground invasion were launched on a northern front from Belarus towards the capital Kyiv, a southern front from Crimea, and an eastern front from the Donbas and towards Kharkiv. Ukraine enacted martial law, ordered a general mobilisation, and severed diplomatic relations with Russia.
Russian troops retreated from the north and the outskirts of Kyiv by April 2022, after encountering stiff resistance and logistical challenges. The Bucha massacre was uncovered after their withdrawal. In the southeast, Russia launched an offensive in the Donbas and captured Mariupol after a destructive siege. Russia continued to bomb military and civilian targets far from the front, and struck the energy grid during winter months. In late 2022, Ukraine launched successful counteroffensives in the south and east, liberating most of Kharkiv Oblast. Soon after, Russia illegally annexed four partly-occupied provinces. In November, Ukraine liberated Kherson. In June 2023, Ukraine launched another counteroffensive in the southeast but made few gains. After small but steady Russian advances in the east in the first half of 2024, Ukraine launched a cross-border offensive into Russia's Kursk Oblast in August, where North Korean soldiers were sent to assist Russia. The United Nations Human Rights Office reports that Russia is committing severe human rights violations in occupied Ukraine. The direct cost of the war for Russia has been over $450 billion.
The invasion was met with widespread international condemnation. The United Nations General Assembly passed a resolution condemning the invasion and demanding a full Russian withdrawal. The International Court of Justice ordered Russia to halt military operations, and the Council of Europe expelled Russia. Many countries imposed sanctions on Russia and its ally Belarus and provided humanitarian and military aid to Ukraine. The Baltic states and Poland declared Russia a terrorist state. Protests occurred around the world, with anti-war protesters in Russia being met by mass arrests and greater media censorship. The Russian attacks on civilians have led to allegations of genocide. War-related disruption to Ukrainian agriculture and shipping contributed to a world food crisis, war-related local environmental damage has been described as ecocide and the war has heavily disrupted global climate policy. The International Criminal Court (ICC) opened an investigation into crimes against humanity, war crimes, abduction of Ukrainian children, and genocide against Ukrainians. The ICC issued arrest warrants for Putin and Maria Lvova-Belova and for four Russian military officials.

## Background
### Post-Soviet relations

After the dissolution of the Soviet Union in December 1991, the newly independent Russian Federation and Ukraine maintained cordial relations. In return for security guarantees, Ukraine signed the Nuclear Non-Proliferation Treaty in 1994 and gave up the Soviet nuclear weapons left in Ukraine. Russia, the US and UK thus agreed in the Budapest Memorandum on Security Assurances to uphold Ukraine's sovereignty and territorial integrity. In 1999, Russia signed the Charter for European Security, affirming the right of each state "to choose or change its security arrangements" and to join alliances. In 2002, Putin said that Ukraine's relations with NATO were "a matter for those two partners". In 2005, Putin said that if Ukraine wanted to join NATO, "we will respect their choice, because it is their sovereign right to decide their own defence policy, and this will not worsen relations between our countries".
Russia invaded Georgia in August 2008 and took control of the breakaway regions of Abkhazia and South Ossetia, demonstrating Russia's willingness to use military force to attain its political objectives. Political scientist Paul D'Anieri says the United States "was accused of appeasement and naivete" over its reaction to the invasion. The West's weak response in 2008—and later in 2014—contributed to Russia's assessment of Western warnings against 2022 invasion as not serious, and, according to political scientist Samuel Ramani, encouraged further Russian aggression.

### Ukrainian revolution

In 2013, Ukraine's parliament overwhelmingly approved finalising an association agreement with the European Union (EU), which had been negotiated for several years. Russia did not raise any concerns about the agreement until mid-2013, when it became clear that Ukraine would no longer be able to maintain the same level of relations with Russia. Russia put pressure on Ukraine to reject the agreement and imposed economic sanctions on the country. Kremlin adviser Sergei Glazyev warned in September 2013 that if Ukraine signed the EU agreement, Russia would no longer acknowledge Ukraine's borders.
In November, Ukrainian president Viktor Yanukovych suddenly withdrew from signing the agreement, choosing closer ties to the Russian-led Eurasian Economic Union instead. This coerced withdrawal triggered a wave of protests known as Euromaidan, culminating in the Revolution of Dignity in February 2014. Almost 100 protesters were killed. Despite signing an agreement, Yanukovych fled. Parliament voted to remove him and he ended up in Russia.

### Russian intervention in Crimea and Donbas

Russian soldiers with no insignia seized the Crimean Parliament and occupied the Ukrainian territory of Crimea, starting the war with Ukraine. Russia annexed Crimea in March 2014, after a widely disputed referendum held under occupation. Historians liken the annexation to Nazi Germany's Anschluss of Austria.
Pro-Russian protests immediately followed in the Ukrainian cities of Donetsk and Luhansk. Separatists proclaimed the Donetsk People's Republic (DPR) and Luhansk People's Republic (LPR). The War in Donbas began in April 2014 when armed Russian mercenaries led by Igor 'Strelkov' Girkin seized Sloviansk and other settlements, and the Ukrainian military began an operation against them. Russia covertly supported the separatists with its own troops, tanks and artillery. The International Criminal Court judged that the war was both a national and international armed conflict involving Russia, and the European Court of Human Rights judged that Russia controlled the DPR and LPR from 2014 onward.
The annexation of Crimea and the Donbas war sparked a wave of Russian nationalism. Analyst Vladimir Socor called Putin's 2014 speech following the annexation a "manifesto of Greater-Russia irredentism". Putin began referring to "Novorossiya" (New Russia), a former Russian imperial territory that covered much of southern Ukraine. Russian-backed forces were influenced by Russian neo-imperialism and sought to create a new Novorossiya. Putin referred to the Kosovo independence precedent and NATO bombing of Yugoslavia as a justification for military intervention in Ukraine.
When the conflict began in 2014, Ukraine was officially a neutral country and was not seeking NATO membership. Because of Russia's occupation of Crimea and its invasion of the Donbas, Ukraine's parliament voted in December 2014 to revoke the country's neutral status and to seek Ukraine's membership in NATO. It was impossible for Ukraine to join NATO at the time, as any applicant country must have no "unresolved external territorial disputes". In 2016, President of the European Commission, Jean-Claude Juncker, said that it would take 20–25 years for Ukraine to join NATO.
The Minsk agreements, signed in September 2014 and February 2015, aimed to resolve the conflict, but ceasefires and further negotiations repeatedly failed.
The West's weak response to Russia's attack on Ukraine in 2014 led Russia to believe that the West would not react strongly to the 2022 invasion. Political scientist Samuel Ramani said this encouraged further Russian aggression.

### Economic aspects

Economic interests were also a motive for Russia's attack on Ukraine and its annexation of the southeast. Control of lithium deposits in the Donbas and Ukraine's grain wealth would give Russia a "monopoly on the world market". In 2022, Russian General Vladimir Ovchinsky confirmed that the "Russian special operation" aimed to seize Ukrainian lithium deposits.
The US government estimates that Russia's economic losses from the war and Western sanctions will amount to around $1.3 trillion by 2025, and Russia's direct financial spending on the invasion is estimated at $250 billion (as of late 2024) – costs that Russia could not have foreseen. According to a study published in mid-2022 by Canadian think tank SecDev, Russia seized energy reserves, metals and minerals worth at least $12.4 trillion in the Donbas, including 41 coal fields (63 percent of Ukraine's coal reserves), 27 natural gas fields, 9 oil fields, 6 iron ore deposits, two titanium ore deposits, a strontium deposit, a uranium deposit, a gold deposit and a large limestone quarry. The total value of raw material stocks in Ukraine is estimated at over $26 trillion. The value of lithium and rare earths in Ukraine is estimated at $11.5 trillion. In January 2024, the Russian occupation government in Donetsk Oblast granted the Russian Ministry of Natural Resources permission to mine lithium in the Shevchenko deposit near Kurakhovo, which is estimated to be worth hundreds of billions of US dollars.
The Russian elite, especially Russian generals, had invested assets and property in Ukraine for money laundering purposes before the invasion.

## Prelude

There was a large Russian military build-up near Ukraine's borders in March and April 2021, and again in both Russia and Belarus from October 2021 onward. Russia said it was only holding military exercises. Members of the Russian government, including Putin, repeatedly denied having plans to attack or invade Ukraine, issuing denials up until the day before the invasion.
While Russian troops massed on Ukraine's borders, Russia's proxy forces launched thousands of attacks on Ukrainian troops in the Donbas. Observers from the Organization for Security and Co-operation in Europe (OSCE), which also includes Ukraine and Russia, reported more than 90,000 ceasefire violations throughout 2021; the vast majority in Russian-controlled territory.
In July 2021, Putin published an essay "On the Historical Unity of Russians and Ukrainians", in which he called Ukraine "historically Russian lands" and claimed there is "no historical basis" for the "idea of Ukrainian people as a nation separate from the Russians". Days before the invasion, Putin claimed that Ukraine never had "real statehood" and that the creation of modern Ukraine was a mistake. Putin was accused of promoting Russian imperialism, historical revisionism and disinformation.
In December 2021, Russia issued an ultimatum to the West, which included demands that NATO end all activity in its Eastern European member states and ban Ukraine or any former Soviet state from ever joining the alliance. Russia's government said NATO was a threat and warned of a military response if it followed an "aggressive line". Some of the demands had already been ruled out by NATO. A senior US official said the US was willing to discuss the proposals, but added that there were some "that the Russians know are unacceptable". Eastern European states willingly joined NATO for security reasons, and the last time a country bordering Russia had joined was in 2004. Ukraine had not yet applied, and some members were wary of letting it join. Barring Ukraine would go against NATO's "open door" policy, and against treaties agreed to by Russia itself. NATO Secretary General Jens Stoltenberg replied that "Russia has no say" on whether Ukraine joins, and "has no right to establish a sphere of influence to try to control their neighbours". NATO underlined that it is a defensive alliance, and that it had co-operated with Russia until the latter annexed Crimea. It offered to improve communication with Russia, and to negotiate limits on missile placements and military exercises, as long as Russia withdrew troops from Ukraine's borders, but Russia did not.
Western leaders vowed that heavy sanctions would be imposed should Putin choose to invade rather than to negotiate. French President Emmanuel Macron and German Chancellor Olaf Scholz met Putin in February 2022 to dissuade him from an invasion. According to Scholz, Putin told him that Ukraine should not be an independent state. Scholz told Ukrainian President Volodymyr Zelenskyy to declare Ukraine a neutral country and renounce its aspirations to join NATO. Zelenskyy replied that Putin could not be trusted, as he had broken agreements before. Ukraine had been a neutral country in 2014 when Russia occupied Crimea and invaded the Donbas. On 19 February, Zelenskyy made a speech at the Munich Security Conference, calling for Western powers to end their "appeasement" towards Putin and give a clear time-frame for when Ukraine could join NATO. Political analysts Taras Kuzio and Vladimir Socor agree that "when Russia made its decision to invade Ukraine, that country was more remote than ever not only from NATO membership but from any track that might lead to membership".
Shortly before the invasion, Russia's proxy forces stepped up attacks on Ukrainian forces and civilians in the Donbas. Separatist leaders warned that Ukraine was about to launch an offensive, but they gave no evidence, and The Guardian noted that it would be "exceedingly risky" for Ukraine to assault the Donbas while Russian troops were massed on its borders. Ukraine and Western leaders accused Russia of staging false flag attacks and of trying to provoke retaliation, to give Russia a pretext for invading. On 17 February, Russian proxy forces shelled a kindergarten in Ukrainian-held territory, then blamed the strike on Ukraine. Zelenskyy said that his military would not respond to the provocations.

### Invasion plans

According to the Royal United Services Institute, Russia's invasion plan involved defeating Ukraine within ten days and capturing or killing its government, followed by "mopping up" operations; establishing filtration camps for Ukrainians; setting up occupation regimes; trying and executing people involved in the Revolution of Dignity; and lastly annexation. The decision to invade was reportedly made by Putin and a small group of war hawks or siloviki in Putin's inner circle, including national security adviser Nikolai Patrushev and defence minister Sergei Shoigu.

### Putin's invasion announcement

On 21 February, Putin announced that Russia recognised the Donetsk People's Republic and Luhansk People's Republic as independent states. The following day, Russia announced that it was sending troops into the territories as "peacekeepers", and the Federation Council of Russia authorised the use of military force abroad.
Before 5 a.m. Kyiv time on 24 February, Putin, in another speech, announced a "special military operation", which effectively declared war on Ukraine. Putin said the operation was to "protect the people" of the Russian-controlled breakaway republics. He baselessly claimed that Russians in the Donbas had "been facing humiliation and genocide perpetrated by the Kyiv regime" for eight years. Putin said that Russia was being threatened: he baselessly claimed that Ukrainian government officials were neo-Nazis under Western control, that Ukraine was developing nuclear weapons, and that a hostile NATO was building up its forces and military infrastructure in Ukraine. He said Russia sought the "demilitarisation and denazification" of Ukraine, and denied the legitimacy of the Ukrainian state. Putin said he had no plans to occupy Ukraine.
The invasion began within minutes of Putin's speech.

## Events

The invasion began at dawn on 24 February. It was described as the biggest attack on a European country and the first full-scale war in Europe since the Second World War, and was Russia's largest combined arms operation since the Soviet Union's Battle of Berlin in 1945. Russia launched a simultaneous ground and air attack. Missiles struck targets throughout Ukraine, and Russian troops invaded from the north, east, and south. Russia did not officially declare war. Immediately after the invasion began, Zelenskyy declared martial law in Ukraine in a first video speech. The same evening, he ordered a general mobilisation of all Ukrainian males between 18 and 60 years old, prohibiting them from leaving the country.
The "first stage" of the invasion was conducted on four fronts, including one towards western Kyiv from Belarus by the Russian Eastern Military District, one deployed towards eastern Kyiv from Russia by the Central Military District (northeastern front), comprised the 41st Combined Arms Army and the 2nd Guards Combined Arms Army, one deployed towards Kharkiv, and a fourth, southern front originating in occupied Crimea and Russia's Rostov oblast with an eastern axis towards Odesa and a western area of operations toward Mariupol. The Russian invasion was unexpectedly met by fierce Ukrainian resistance. In Kyiv, Russia failed to take the city and was repulsed in the battles of Irpin, Hostomel, and Bucha. The Russians tried to encircle the capital, but its defenders under Oleksandr Syrskyi held their ground, effectively using Western Javelin anti-tank missiles and Stinger anti-aircraft missiles to thin Russian supply lines and stall the offensive.
By 7 April, Russian troops deployed to the northern front by the Russian Eastern Military District pulled back from the Kyiv offensive, reportedly to resupply and redeploy to the Donbas region in an effort to reinforce the renewed invasion of southeastern Ukraine. The northeastern front, including the Central Military District, was similarly withdrawn for resupply and redeployment to southeastern Ukraine. On 26 April, delegates from the US and 40 allied nations met at Ramstein Air Base in Germany to discuss the formation of a coalition that would provide economic support in addition to military supplies and refitting to Ukraine. Following Putin's Victory Day speech in early May, US Director of National Intelligence Avril Haines said no short term resolution to the invasion should be expected.
Ukraine's reliance on Western-supplied equipment constrained operational effectiveness, as supplying countries feared that Ukraine would use Western-made matériel to strike targets in Russia. Military experts disagreed on the future of the conflict; some suggested that Ukraine should trade territory for peace, while others believed that Ukraine could maintain its resistance due to Russian losses.

### Initial invasion (24 February – 7 April 2022)

The invasion began on 24 February, launched out of Belarus to target Kyiv, and from the northeast against the city of Kharkiv. The southeastern front was conducted as two separate spearheads, from Crimea and the southeast against Luhansk and Donetsk.

#### Kyiv and northern front

Russian tried to seize Kyiv quickly with a probative spearhead on 24 February, from Belarus south along the west bank of the Dnipro River, with Spetsnaz infiltrating into the city supported by airborne operations and a rapid mechanised advance from the north, but failed. The apparent intent was to encircle the city from the west, supported by two separate axes of attack from Russia along the east bank of the Dnipro: the western at Chernihiv, and from the east at Sumy. These were likely intended to encircle Kyiv from the northeast and east.
Russian forces advanced into Chernihiv Oblast on 24 February, besieging its administrative capital within four days of fighting. On 25 February Ukrainian forces lost control over Konotop. As street fighting took place in the city of Sumy, just 35 kilometres (22 mi) from the Russo-Ukrainian border, Ukrainian forces claimed that on 28 February that 100 Russian armoured vehicles had been destroyed and dozens of soldiers captured following a Bayraktar TB2 drone and artillery attack on a large Russian column near Lebedyn in Sumy Oblast. Russian forces also attacked Okhtyrka, deploying thermobaric weapons. Travelling along highways, Russian forces reached Brovary, an eastern suburb of Kyiv, on 4 March.
The United States contacted Zelenskyy and offered to help him flee the country, lest the Russian Army attempt to kidnap or kill him on seizing Kyiv; Zelenskyy responded that "The fight is here; I need ammunition, not a ride." By early March, Russian advances along the west side of the Dnipro were limited by Ukrainian defences. As of 5 March, a large Russian convoy, reportedly 64 kilometres (40 mi) long, had made little progress toward Kyiv. Advances from Chernihiv largely halted as a siege began there. Russian forces continued to advance on Kyiv from the northwest, capturing Bucha, Hostomel and Vorzel by 5 March, though Irpin remained contested as of 9 March. By 11 March, the lengthy convoy had largely dispersed and taken cover. On 16 March, Ukrainian forces began a counter-offensive to repel Russian forces. Unable to achieve a quick victory in Kyiv, Russian forces switched their strategy to indiscriminate bombing and siege warfare.
On 25 March, a Ukrainian counter-offensive retook several towns to the east and west of Kyiv, including Makariv. Russian troops in the Bucha area retreated north at the end of March. Ukrainian forces entered the city on 1 April, and recaptured the entire region around Kyiv, including Irpin, Bucha, and Hostomel, and uncovered evidence of war crimes in Bucha. The Pentagon confirmed on 6 April that the Russian army had left Chernihiv Oblast, but Sumy Oblast remained contested; NATO secretary-general Jens Stoltenberg said that the Russian "retraction, resupply, and redeployment" of their troops from the Kyiv area should be interpreted as an expansion of Putin's plans for Ukraine, by redeploying and concentrating his forces on eastern Ukraine. On 7 April, the governor of Sumy Oblast said that Russian troops were gone, but had left behind rigged explosives and other hazards.

#### Southern and eastern front

On 24 February, Russian forces took control of the North Crimean Canal, allowing Crimea to obtain water from the Dnieper, which had been cut off since 2014. On 26 February, the siege of Mariupol began as the attack moved east linking to separatist-held Donbas. En route, Russian forces entered Berdiansk and captured it. On 25 February, Russian units from the DPR were fighting near Pavlopil as they moved on Mariupol. By evening, the Russian Navy began an amphibious assault on the coast of the Sea of Azov 70 kilometres (43 mi) west of Mariupol. A US defence official said that Russian forces were deploying thousands of marines from this beachhead.
In the east, Russian troops attempted to capture Kharkiv, less than 35 kilometres (22 mi) from the Russian border, and met strong Ukrainian resistance. On 25 February, the Millerovo air base was attacked by Ukrainian military forces with OTR-21 Tochka missiles, which according to Ukrainian officials, destroyed several Russian Air Force planes and started a fire. On 1 March, Denis Pushilin, head of the DPR, announced that DPR forces had almost completely surrounded the city of Volnovakha. On 2 March, Russian forces were repelled from Sievierodonetsk during an attack against the city. On the same day, Ukrainian forces initiated a counter-offensive on Horlivka, controlled by the DPR. Izium was captured by Russian forces on 1 April after a monthlong battle. On 25 March, the Russian defence ministry said it would seek to occupy major cities in eastern Ukraine. On 31 March, PBS News reported renewed shelling and missile attacks in Kharkiv, as bad or worse than before, as peace talks with Russia were to resume in Istanbul.
The Russian 22nd Army Corps approached the Zaporizhzhia Nuclear Power Plant on 26 February and besieged Enerhodar. A fire began, but the Ukrainian military said that essential equipment was undamaged. A third Russian attack group from Crimea moved northwest and captured the bridge over the Dnieper. On 2 March, Russian troops took Kherson; this was the first major city to fall to Russian forces. Russian troops moved on Mykolaiv and attacked it two days later. They were repelled by Ukrainian forces.
After renewed missile attacks on 14 March in Mariupol, the Ukrainian government said more than 2,500 had died. By 18 March, Mariupol was completely encircled and fighting reached the city centre, hampering efforts to evacuate civilians. On 20 March, an art school sheltering around 400 people, was destroyed by Russian bombs. The Russians demanded surrender, and the Ukrainians refused. On 27 March, Ukrainian deputy prime minister Olha Stefanishyna said that "(m)ore than 85 percent of the whole town is destroyed." Putin told Emmanuel Macron in a phone call on 29 March that the bombardment of Mariupol would only end when the Ukrainians surrendered. On 1 April, Russian troops refused safe passage into Mariupol to 50 buses sent by the United Nations to evacuate civilians, as peace talks continued in Istanbul. On 3 April, following the retreat of Russian forces from Kyiv, Russia expanded its attack on southern Ukraine further west, with bombardment and strikes against Odesa, Mykolaiv, and the Zaporizhzhia Nuclear Power Plant. On 31 March, Russia reported a helicopter strike against an oil supply depot approximately 35 kilometres (22 mi) north of the border in Belgorod, and accused Ukraine of the attack; Ukraine denied responsibility. By 7 April, the renewed massing of Russian invasion troops and tank divisions around the towns of Izium, Sloviansk, and Kramatorsk prompted Ukrainian government officials to advise the remaining residents near the eastern border of Ukraine to evacuate to western Ukraine within 2–3 days, given the absence of arms and munitions previously promised to Ukraine by then.

### Southeastern front (8 April – 5 September 2022)

By 17 April, Russian progress on the southeastern front appeared to be impeded by opposing Ukrainian forces in the large, heavily fortified Azovstal steel mill and surrounding area in Mariupol.
On 19 April, The New York Times confirmed that Russia had launched a renewed invasion front referred to as an "eastern assault" across a 480-kilometre (300 mi) front extending from Kharkiv to Donetsk and Luhansk, with simultaneous missile attacks again directed at Kyiv in the north and Lviv in western Ukraine. As of 30 April, a NATO official described Russian advances as "uneven" and "minor." An anonymous US Defence official called the Russian offensive "very tepid", "minimal at best", and "anaemic."
By 30 May, disparities between Russian and Ukrainian artillery were apparent, with Ukrainian artillery being vastly outgunned, in terms of both range and number. In response to US President Joe Biden's indication that enhanced artillery would be provided to Ukraine, Putin said that Russia would expand its invasion front to include new cities in Ukraine. In apparent retribution, Putin ordered a missile strike against Kyiv on 6 June after not directly attacking the city for several weeks. On 10 June 2022, deputy head of the SBU Vadym Skibitsky stated that during the Sievierodonetsk campaign, the frontlines were where the future of the invasion would be decided:
   This is an artillery war now, and we are losing in terms of artillery. Everything now depends on what [the west] gives us. Ukraine has one artillery piece to 10 to 15 Russian artillery pieces. Our western partners have given us about 10% of what they have.
On 29 June, Reuters reported that US Intelligence Director Avril Haines, in an update of past US intelligence assessments on the Russian invasion, said that US intelligence agencies agree that the invasion will continue "for an extended period of time ... In short, the picture remains pretty grim and Russia's attitude toward the West is hardening." On 5 July, BBC reported that extensive destruction by the Russian invasion would cause immense financial damage to Ukraine's reconstruction economy, with Ukrainian Prime Minister Denys Shmyhal telling nations at a reconstruction conference in Switzerland that Ukraine needs $750B for a recovery plan and Russian oligarchs should contribute to the cost.
In June 2022 the chief spokesman for the Russian Ministry of Defence Igor Konashenkov revealed that Russian troops were divided between the Army Groups "Centre" commanded by Colonel General Aleksander Lapin and "South" commanded by Army General Sergey Surovikin. On 20 July, Lavrov announced that Russia would respond to the increased military aid being received by Ukraine from abroad as justifying the expansion of its special military operation to include objectives in both the Zaporizhzhia and Kherson oblasts.
Russian Ground Forces started recruiting volunteer battalions from the regions in June 2022 to create a new 3rd Army Corps within the Western Military District, with a planned strength estimated at 15,500–60,000 personnel. Its units were deployed to the front around the time of Ukraine's 9 September Kharkiv oblast counteroffensive, in time to join the Russian retreat, leaving behind tanks, infantry fighting vehicles, and personnel carriers: the 3rd Army Corps "melted away" according to Forbes, having little or no impact on the battlefield along with other irregular forces.

#### Fall of Mariupol

On 13 April, Russian forces intensified their attack on the Azovstal Iron and Steel Works in Mariupol, and the remaining Ukrainian personnel defending it. By 17 April, Russian forces had surrounded the factory. Ukrainian prime minister Denys Shmyhal said that the Ukrainian soldiers had vowed to ignore the renewed ultimatum to surrender and to fight to the last soul. On 20 April, Putin said that the siege of Mariupol could be considered tactically complete, since the 500 Ukrainian troops entrenched in bunkers within the Azovstal iron works and estimated 1,000 Ukrainian civilians were completely sealed off from any type of relief.
After consecutive meetings with Putin and Zelenskyy, UN Secretary-General Guterres on 28 April said he would attempt to organise an emergency evacuation of survivors from Azovstal in accordance with assurances he had received from Putin on his visit to the Kremlin. On 30 April, Russian troops allowed civilians to leave under UN protection. By 3 May, after allowing approximately 100 Ukrainian civilians to depart from the Azovstal steel factory, Russian troops renewed their bombardment of the steel factory. On 6 May, The Daily Telegraph reported that Russia had used thermobaric bombs against the remaining Ukrainian soldiers, who had lost contact with the Kyiv government; in his last communications, Zelenskyy authorised the commander of the besieged steel factory to surrender as necessary under the pressure of increased Russian attacks. On 7 May, the Associated Press reported that all civilians were evacuated from the Azovstal steel works at the end of the three-day ceasefire.
After the last civilians evacuated from the Azovstal bunkers, nearly two thousand Ukrainian soldiers remained barricaded there, 700 of them injured. They were able to communicate a plea for a military corridor to evacuate, as they expected summary execution if they surrendered to Russian forces. Reports of dissent within the Ukrainian troops at Azovstal were reported by Ukrainska Pravda on 8 May indicating that the commander of the Ukrainian marines assigned to defend the Azovstal bunkers made an unauthorised acquisition of tanks, munitions, and personnel, broke out from the position there and fled. The remaining soldiers spoke of a weakened defensive position in Azovstal as a result, which allowed progress to advancing Russian lines of attack. Ilia Somolienko, deputy commander of the remaining Ukrainian troops barricaded at Azovstal, said: "We are basically here dead men. Most of us know this and it's why we fight so fearlessly."
On 16 May, the Ukrainian General staff announced that the Mariupol garrison had "fulfilled its combat mission" and that final evacuations from the Azovstal steel factory had begun. The military said that 264 service members were evacuated to Olenivka under Russian control, while 53 of them who were "seriously injured" had been taken to a hospital in Novoazovsk also controlled by Russian forces. Following the evacuation of Ukrainian personnel from Azovstal, Russian and DPR forces fully controlled all areas of Mariupol. The end of the battle also brought an end to the Siege of Mariupol. Russia press secretary Dmitry Peskov said Russian President Vladimir Putin had guaranteed that the fighters who surrendered would be treated "in accordance with international standards" while Ukrainian President Volodymyr Zelenskyy said in an address that "the work of bringing the boys home continues, and this work needs delicacy—and time." Some prominent Russian lawmakers called on the government to deny prisoner exchanges for members of the Azov Regiment.

#### Fall of Sievierodonetsk and Lysychansk

A Russian missile attack on Kramatorsk railway station in the city of Kramatorsk took place on 8 April, reportedly killing at least 61 people and injuring as many as 87 to 300. On 11 April, Zelenskyy said that Ukraine expected a major new Russian offensive in the east. American officials said that Russia had withdrawn or been repulsed elsewhere in Ukraine, and therefore was preparing a retraction, resupply, and redeployment of infantry and tank divisions to the southeastern Ukraine front. Military satellites photographed extensive Russian convoys of infantry and mechanised units deploying south from Kharkiv to Izium on 11 April, apparently part of the planned Russian redeployment of its northeastern troops to the southeastern front of the invasion.
On 18 April, with Mariupol almost entirely overtaken by Russian forces, the Ukrainian government announced that the second phase of the reinforced invasion of the Donetsk, Luhansk and Kharkiv oblasts had intensified with expanded invasion forces occupying of the Donbas.
On 22 May, the BBC reported that after the fall of Mariupol, Russia had intensified offensives in Luhansk and Donetsk while concentrating missile attacks and intense artillery fire on Sievierodonetsk, the largest city under Ukrainian control in Luhansk Oblast.
On 23 May, Russian forces were reported entering the city of Lyman, fully capturing the city by 26 May. Ukrainian forces were reported leaving Sviatohirsk. By 24 May, Russian forces captured the city of Svitlodarsk. On 30 May, Reuters reported that Russian troops had breached the outskirts of Sievierodonetsk. By 2 June, The Washington Post reported that Sievierodonetsk was on the brink of capitulation to Russian occupation with over 80 per cent of the city in the hands of Russian troops. On 3 June, Ukrainian forces reportedly began a counter-attack in Sievierodonetsk. By 4 June, Ukrainian government sources claimed 20% or more of the city had been recaptured.
On 12 June, it was reported that possibly as many as 800 Ukrainian civilians (as per Ukrainian estimates) and 300–400 soldiers (as per Russian sources) were besieged at the Azot chemical factory in Sievierodonetsk. With the Ukrainian defences of Sievierodonetsk faltering, Russian invasion troops began intensifying their attack upon the neighbouring city of Lysychansk as their next target city in the invasion. On 20 June it was reported that Russian troops continued to tighten their grip on Sievierodonetsk by capturing surrounding villages and hamlets surrounding the city, most recently the village of Metelkine.
On 24 June, CNN reported that, amid continuing scorched-earth tactics being applied by advancing Russian troops, Ukraine's armed forces were ordered to evacuate the Sievierodonetsk; several hundred civilians taking refuge in the Azot chemical plant were left behind in the withdrawal, with some comparing their plight to that of the civilians at the Azovstal steel works in Mariupol in May. On 3 July, CBS announced that the Russian defence ministry claimed that the city of Lysychansk had been captured and occupied by Russian forces. On 4 July, The Guardian reported that after the fall of the Luhansk oblast, that Russian invasion troops would continue their invasion into the adjacent Donetsk Oblast to attack the cities of Sloviansk and Bakhmut.

#### Kharkiv front

On 14 April, Ukrainian troops reportedly blew up a bridge between Kharkiv and Izium used by Russian forces to redeploy troops to Izium, impeding the Russian convoy.
On 5 May, David Axe writing for Forbes stated that the Ukrainian army had concentrated its 4th and 17th Tank Brigades and the 95th Air Assault Brigade around Izium for possible rearguard action against the deployed Russian troops in the area; Axe added that the other major concentration of Ukraine's forces around Kharkiv included the 92nd and 93rd Mechanised Brigades which could similarly be deployed for rearguard action against Russian troops around Kharkiv or link up with Ukrainian troops contemporaneously being deployed around Izium.
On 13 May, BBC reported that Russian troops in Kharkiv were being retracted and redeployed to other fronts in Ukraine following the advances of Ukrainian troops into surrounding cities and Kharkiv itself, which included the destruction of strategic pontoon bridges built by Russian troops to cross over the Seversky Donets river and previously used for rapid tank deployment in the region.

#### Kherson-Mykolaiv front

Missile attacks and bombardment of the key cities of Mykolaiv and Odesa continued as the second phase of the invasion began. On 22 April 2022, Russia's Brigadier General Rustam Minnekayev in a defence ministry meeting said that Russia planned to extend its Mykolaiv–Odesa front after the siege of Mariupol further west to include the breakaway region of Transnistria on the Ukrainian border with Moldova. The Ministry of Defence of Ukraine called this plan imperialism and said that it contradicted previous Russian claims that it did not have territorial ambitions in Ukraine and also that the statement admitted that "the goal of the 'second phase' of the war is not victory over the mythical Nazis, but simply the occupation of eastern and southern Ukraine." Georgi Gotev of EURACTIV noted on 22 April that Russian occupation from Odesa to Transnistria would transform Ukraine into a landlocked nation with no practical access to the Black Sea. Russia resumed its missile strikes on Odesa on 24 April, destroying military facilities and causing two dozen civilian casualties.
Explosions destroyed two Russian broadcast towers in Transnistria on 27 April that had primarily rebroadcast Russian television programming, Ukrainian sources said. Russian missile attacks at the end of April destroyed runways in Odesa. In the week of 10 May, Ukrainian troops began to dislodge Russian forces from Snake Island in the Black Sea approximately 200 kilometres (120 mi) from Odesa. Russia said on 30 June 2022 that it had withdrawn its troops from the island, once their objectives had been completed.
On 23 July, CNBC reported a Russian missile strike on the Ukrainian port of Odesa, swiftly condemned by world leaders amid a recent UN- and Turkish-brokered deal to secure a sea corridor for exports of grains and other foodstuffs. On 31 July, CNN reported significantly intensified rocket attacks and bombing of Mykolaiv by Russians, which also killed Ukrainian grain tycoon Oleksiy Vadaturskyi.

#### Zaporizhzhia front

Russian forces continued to fire missiles and drop bombs on the key cities of Dnipro and Zaporizhzhia. Russian missiles destroyed the Dnipro International Airport on 10 April 2022. On 2 May, the UN, reportedly with the cooperation of Russian troops, evacuated about 100 survivors from the siege of Mariupol to the village of Bezimenne near Donetsk, from whence they would move to Zaporizhzhia. On 28 June, Reuters reported that a Russian missile attack on the city of Kremenchuk northwest of Zaporizhzhia detonated in a public mall and caused at least 18 deaths. France's Emmanuel Macron called it a "war crime."
Ukrainian nuclear agency Energoatom called the situation at the Zaporizhzhia nuclear power plant "extremely tense", although it was still operated by its Ukrainian staff. As many as 500 Russian soldiers controlled the plant; Kyiv's nuclear agency said they were shelling nearby areas and storing weapons and "missile systems" there. Almost the entire country went on air raid alert. "They already shell the other side of the river Dnipro and the territory of Nikopol," Energoatom president Pedro Kotin said. Russia agreed on 19 August to allow IAEA inspectors access to the Zaporizhzhia plant after a phone call from Macron to Putin. As of July 2023, access to the plant remained limited and required extensive negotiation.
Russia reported that 12 attacks with explosions from 50 artillery shells had been recorded by 18 August at the plant and the company town of Enerhodar. Tobias Ellwood, chair of the UK's Defence Select Committee, said on 19 August that any deliberate damage to the Zaporizhzhia nuclear plant that could cause radiation leaks would be a breach of Article 5 of the North Atlantic Treaty, under which an attack on a member state of NATO is an attack on them all. US congressman Adam Kinzinger said the following day that any radiation leak would kill people in NATO countries, an automatic activation of Article 5.
Shelling hit coal ash dumps at the neighbouring coal-fired power station on 23 August, and the ash was on fire on 25 August. The 750 kV transmission line to the Dniprovska substation, the only one of the four 750 kV transmission lines still undamaged and cut by military action, passes over the ash dumps. At 12:12 p.m. on 25 August, the line was cut off due to the fire, disconnecting the plant and its two operating reactors from the national grid for the first time since its startup in 1985. In response, backup generators and coolant pumps for reactor 5 started up, and reactor 6 reduced generation.
Incoming power was still available across the 330 kV line to the substation at the coal-fired station, so the diesel generators were not essential for cooling reactor cores and spent fuel pools. The 750 kV line and reactor 6 resumed operation at 12:29 p.m., but the line was cut by fire again two hours later. The line, but not the reactors, resumed operation again later that day. On 26 August, one reactor restarted in the afternoon and another in the evening, resuming electricity supplies to the grid. On 29 August 2022, an IAEA team led by Rafael Grossi went to the plant to investigate. Lydie Evrard and Massimo Aparo were also on the team. No leaks had been reported at the plant before their arrival, but shelling had occurred days before.

### Russian annexations and occupation losses (6 September – 11 November 2022)

On 6 September 2022, Ukrainian forces launched a surprise counteroffensive in the Kharkiv region, beginning near Balakliia, led by General Syrskyi. An emboldened Kyiv launched a counteroffensive 12 September around Kharkiv successful enough to make Russia admit losing key positions and for The New York Times to say that it dented the image of a "Mighty Putin". Kyiv sought more arms from the West to sustain the counteroffensive. On 21 September 2022, Vladimir Putin announced a partial mobilisation and Minister of Defence Sergei Shoigu said 300,000 reservists would be called. He also said that his country would use "all means" to "defend itself." Mykhailo Podolyak, an adviser to Zelenskyy, said that the decision was predictable and that it was an attempt to justify "Russia's failures." British Foreign Office Minister Gillian Keegan called the situation an "escalation", while former Mongolian president Tsakhiagiin Elbegdorj accused Russia of using Russian Mongols as "cannon fodder."

#### Russian annexation of Donetsk, Kherson, Luhansk and Zaporizhzhia oblasts

In late September 2022, Russian-installed officials in Ukraine organised referendums on the annexation of the occupied territories of Ukraine. These included the Donetsk People's Republic and the Luhansk People's Republic in Russian-occupied Donetsk and Luhansk oblasts of Ukraine, as well as the Russian-appointed military administrations of Kherson Oblast and Zaporizhzhia Oblast. Denounced by Ukraine's government and its allies as sham elections, the elections' official results showed overwhelming majorities in favour of annexation.
On 30 September 2022, Vladimir Putin announced the annexation of Ukraine's Donetsk, Luhansk, Kherson and Zaporizhzhia oblasts in an address to both houses of the Russian parliament. Ukraine, the United States, the European Union and the United Nations all denounced the annexation as illegal.

#### Zaporizhzhia front

An IAEA delegation visited the Zaporizhzhia nuclear power plant on 3 September, and on 6 September reported damage and security threats caused by external shelling and the presence of occupying troops in the plant. On 11 September, at 3:14 a.m., the sixth and final reactor was disconnected from the grid, "completely stopping" the plant. Energoatom said that preparations were "underway for its cooling and transfer to a cold state."
In the early hours of 9 October 2022, Russian Armed Forces carried out an airstrike on a residential building in Zaporizhzhia, killing 13 civilians and injuring 89 others.

#### Kherson counteroffensive

On 29 August, Zelenskyy advisedly vowed the start of a full-scale counteroffensive in the southeast. He first announced a counteroffensive to retake Russian-occupied territory in the south concentrating on the Kherson-Mykolaiv region, a claim that was corroborated by the Ukrainian parliament as well as Operational Command South.
On 4 September, Zelenskyy announced the liberation of two unnamed villages in Kherson Oblast and one in Donetsk Oblast. Ukrainian authorities released a photo showing the raising of the Ukrainian flag in Vysokopillia by Ukrainian forces. Ukrainian attacks also continued along the southern frontline, though reports about territorial changes were largely unverifiable. On 12 September, Zelenskyy said that Ukrainian forces had retaken a total of 6,000 square kilometres (2,300 sq mi) from Russia, in both the south and the east. The BBC stated that it could not verify these claims.
In October, Ukrainian forces pushed further south towards the city of Kherson, taking control of 1,170 square kilometres (450 sq mi) of territory, with fighting extending to Dudchany. On 9 November, defence minister Shoigu ordered Russian forces to leave part of Kherson Oblast, including the city of Kherson, and move to the eastern bank of the Dnieper. On 11 November, Ukrainian troops entered Kherson, as Russia completed its withdrawal. This meant that Russian forces no longer had a foothold on the west (right) bank of the Dnieper.

#### Kharkiv counteroffensive

Ukrainian forces launched another surprise counteroffensive on 6 September in the Kharkiv Oblast near Balakliia led by General Syrskyi. By 7 September, Ukrainian forces had advanced some 20 kilometres (12 mi) into Russian occupied territory and claimed to have recaptured approximately 400 square kilometres (150 sq mi). Russian commentators said this was likely due to the relocation of Russian forces to Kherson in response to the Ukrainian offensive there. On 8 September, Ukrainian forces captured Balakliia and advanced to within 15 kilometres (9.3 mi) of Kupiansk. Military analysts said Ukrainian forces appeared to be moving towards Kupiansk, a major railway hub, with the aim of cutting off the Russian forces at Izium from the north.
On 9 September, the Russian occupation administration of Kharkiv Oblast announced it would "evacuate" the civilian populations of Izium, Kupiansk and Velykyi Burluk. The Institute for the Study of War (ISW) said it believed Kupiansk would likely fall in the next 72 hours, while Russian reserve units were sent to the area by both road and helicopter. On the morning of 10 September, photos emerged claiming to depict Ukrainian troops raising the Ukrainian flag in the centre of Kupiansk, and the ISW said Ukrainian forces had captured approximately 2,500 square kilometres (970 sq mi) by effectively exploiting their breakthrough. Later in the day, Reuters reported that Russian positions in northeast Ukraine had "collapsed" in the face of the Ukrainian assault, with Russian forces forced to withdraw from their base at Izium after being cut off by the capture of Kupiansk.
By 15 September, an assessment by UK's Ministry of Defence confirmed that Russia had either lost or withdrawn from almost all of their positions west of the Oskil river. The retreating units had also abandoned various high-value military assets. The offensive continued pushing east and by 1 October, Ukrainian Armed Forces had liberated the key city of Lyman.

### Winter stalemate, attrition campaign and 1st military surge (12 November 2022 – 7 June 2023)

After the end of the twin Ukrainian counteroffensives, the fighting shifted to a semi-deadlock during the winter, with heavy casualties but reduced motion of the frontline. Russia launched a self-proclaimed winter offensive in eastern Ukraine, but the campaign ended in "disappointment" for Moscow, with limited gains as the offensive stalled. Analysts variously blamed the failure on Russia's lack of "trained men", and supply problems with artillery ammunition, among other problems. Near the end of May, Mark Galeotti assessed that "after Russia's abortive and ill-conceived winter offensive, which squandered its opportunity to consolidate its forces, Ukraine is in a relatively strong position."
On 7 February, The New York Times reported that Russians had newly mobilised nearly 200,000 soldiers to participate in the offensive in the Donbas, against Ukraine troops already wearied by previous fighting. The Russian private military company Wagner Group took on greater prominence in the war, leading "grinding advances" in Bakhmut with tens of thousands of recruits from prison battalions taking part in "near suicidal" assaults on Ukrainian positions.
In late January 2023, fighting intensified in southern Zaporizhzhia Oblast, with both sides suffering heavy casualties. In nearby southern parts of Donetsk Oblast, an intense, three-week Russian assault near the coal-mining town of Vuhledar was called the largest tank battle of the war to date, and ended in disaster for Russian forces, who lost "at least 130 tanks and armored personnel carriers" according to Ukrainian commanders. The British Ministry of Defence stated that "a whole Russian brigade was effectively annihilated."
In late 2022, as Russian casualties exceeded 50,000, the Russian army introduced barrier troops. The U.K. defence ministry stated that these are units that threaten to shoot their own retreating soldiers in order to compel offensives. In March 2023, Russian soldiers filmed a video addressed to President Putin where they stated that after suffering casualties, they attempted to return to their headquarters but their superiors denied them evacuation. They stated that barrier troops were placed behind them threatening to "destroy them". In particular, Storm-Z units have been reported to be "kept in line" by barrier troops.

### Battle of Bakhmut

Following defeat in Kherson and Kharkiv, Russian and Wagner forces focused on taking the city of Bakhmut and breaking the half year long stalemate that prevailed there since the start of the war. Russian forces sought to encircle the city, attacking from the north via Soledar. After taking heavy casualties, Russian and Wagner forces took control of Soledar on 16 January 2023. By early February 2023, Bakhmut was facing attacks from north, south and east, with the sole Ukrainian supply lines coming from Chasiv Yar to the west.
On 3 March 2023, Ukrainian soldiers destroyed two key bridges, creating the possibility for a controlled fighting withdrawal from eastern sectors of Bakhmut. On 4 March, Bakhmut's deputy mayor told news services that there was street fighting in the city. On 7 March, despite the city's near-encirclement, The New York Times reported that Ukrainian commanders were requesting permission from Kyiv to continue fighting against the Russians in Bakhmut.
On 26 March, Wagner Group forces claimed to have fully captured the tactically significant Azom factory in Bakhmut. Appearing before the House Committee on Armed Services on 29 March, General Mark Milley, Chairman of the Joint Chiefs of Staff, reported that, "for about the last 20, 21 days, the Russia have not made any progress whatsoever in and around Bakhmut." Milley described the severe casualties being inflicted upon the Russian forces there as a "slaughter-fest."
By the beginning of May, the ISW assessed that Ukraine controlled only 1.89 square kilometres (0.73 sq mi) of the city, less than five percent. On 18 May 2023, The New York Times reported that Ukrainian forces had launched a local counteroffensive, taking back swathes of territory to the north and south of Bakhmut over the course of a few days. On 20 May 2023, the Wagner Group claimed full control over Bakhmut, and a victory in the battle was officially declared by Russia the next day, following which Wagner forces retreated from the city in place of regular Russian units.

### 2023 Ukrainian counteroffensives (8 June 2023 – 1 December 2023)

In June 2023, Ukrainian forces gradually launched a series of counteroffensives on multiple fronts, including Donetsk Oblast, Zaporizhzhia Oblast, and others. On 8 June 2023, counteroffensive efforts focused near settlements such as Orikhiv, Tokmak, and Bakhmut. Counteroffensive operations faced stiff resistance from Russia, and the American think tank Institute for the Study of War described the Russian defensive effort as having "an uncharacteristic degree of coherency." By 12 June, Ukraine reported its fastest advance in seven months, claiming to have liberated several villages and advanced a total of 6.5 km. Russian military bloggers also reported that Ukraine had taken Blahodatne, Makarivka and Neskuchne, and were continuing to push southward. Ukraine continued to liberate settlements over the next few months, raising the Ukrainian flag over the settlement of Robotyne in late August.
On 24 June, the Wagner Group launched a brief rebellion against the Russian government, capturing several cities in western Russia largely unopposed before marching towards Moscow. This came as the culmination of prolonged infighting and power struggles between Wagner and the Russian Ministry of Defence. After about 24 hours, the Wagner Group backed down and agreed to a peace deal in which Wagner leader Yevgeny Prigozhin would go into exile in Belarus, and his forces would be free from prosecution. On 27 June, the UK's Ministry of Defence reported that Ukraine were "highly likely" to have reclaimed territory in the eastern Donbas region occupied by Russia since 2014 among its advances. Pro-Russian bloggers also reported that Ukrainian forces had made gains in the southern Kherson Oblast, establishing a foothold on the left bank of the Dnipro river.
In August, The Guardian reported that Ukraine had become the most mined country in the world, with Russia laying millions of mines attempting to thwart Ukraine's counteroffensive. The vast minefields forced Ukraine to extensively de-mine areas to allow advances. Ukrainian officials reported shortages of men and equipment as Ukrainian soldiers unearthed five mines for every square metre in certain places.
Following Russia pulling out of the Black Sea Grain Initiative, the conflict on the Black Sea escalated with Ukraine targeting Russian ships. On 4 August, Ukrainian security service sources reported that the Russian landing ship Olenegorsky Gornyak had been hit and damaged by an unmanned naval drone. Video footage released by Ukraine's security services appeared to show the drone striking the ship, with another video showing the ship seemingly listing to one side. On 12 September, both Ukrainian and Russian sources reported that Russian naval targets in Sevastopol had been struck by unconfirmed weaponry, damaging two military vessels, one of them reportedly a submarine. Ukraine also reported that several oil and gas drilling platforms on the Black Sea held by Russia since 2015 had been retaken.
In September 2023, Ukrainian intelligence estimated that Russia had deployed over 420,000 troops in Ukraine.
On 21 September, Russia began missile strikes across Ukraine, damaging the country's energy facilities. On 22 September, the US announced it would send long-range ATACMS missiles to Ukraine, despite the reservations of some government officials. The same day, the Ukrainian Main Directorate of Intelligence launched a missile strike on the Black Sea Fleet headquarters in Sevastopol, Crimea, killing several senior military officials.
In mid-to-late October 2023, Ukrainian marines—partly guided by defecting Russian troops—crossed the Dnipro River (the strategic barrier between eastern and western Ukraine), downstream of the destroyed Kakhovka Dam, to attack the Russian-held territory on the east side of the river. Despite heavy losses due to intense Russian shelling and aerial bombardment, disorganisation, and dwindling resources, Ukrainian brigades invading the Russian-held side of the river continued to inflict heavy casualties on Russian forces well into late December.
On 1 December 2023, Volodymyr Zelenskyy stated that the Ukrainian counter-offensive was not successful, citing slower than expected results. Zelenskyy also stated that it will be easier for Ukraine to regain the Crimean peninsula than the Donbas region in the east of the country, because the Donbas is heavily militarised and there are frequent pro-Russian sentiments. In December 2023, multiple international media outlets described the Ukrainian counteroffensive as having failed to regain any significant amount of territory or meet any of its strategic objectives.

### Battle of Avdiivka

In October 2023, it was reported that there was a growth of mutinies among Russian troops due to the large number of losses in Russian offensives around Avdiivka with a lack of artillery, food, water and poor command also being reported. By November, British intelligence said that recent weeks had "likely seen some of the highest Russian casualty rates of the war so far."
On 17 February 2024, Russia captured Avdiivka, a longtime stronghold for Ukraine that had been described as a "gateway" to nearby Donetsk. ABC News stated that Russia could use the development to boost morale with the war largely at a stalemate close to its second anniversary. Described by Forbes journalist David Axe as a pyrrhic Russian victory, the Russian 2nd and 41st Combined Arms Armies ended up with 16,000 men killed, tens of thousands wounded and around 700 vehicles lost before seizing the ruins of Avdiivka.
Ukraine's shortage of ammunition caused by political deadlock in the US Congress and a lack of production capacity in Europe contributed to the Ukrainian withdrawal from Avdiivka, and was "being felt across the front" according to Time. The shortage resulted in Ukraine having to ration its units to fire only 2,000 rounds per day, compared to an estimated 10,000 rounds fired daily by Russia.

### Russian offensives and Ukrainian incursion (April 2024 – present)
#### Russian spring and summer offensives

On 10 May 2024, Russia began a renewed offensive in Kharkiv Oblast. Russia managed to capture a dozen villages, and Ukraine had evacuated more than 11,000 people from the region since the start of the offensive by 25 May. Ukraine said on 17 May that its forces had slowed the Russian advance, and by 25 May Zelenskyy said that Ukrainian forces had secured "combat control" of areas where Russian troops entered the northeastern Kharkiv Oblast. Russian officials said that they were "advancing in every direction" and that the goal was to create a "buffer zone" for embattled border regions. The White House said on 7 June that the offensive had stalled and was unlikely to advance further.
Following the Russian success in the battle of Avdiivka, their forces advanced northwest of it to form a salient, and by mid-April 2024 reached the settlement of Ocheretyne, capturing it in late April and further expanding the salient in the succeeding months. Russian forces also launched an offensive towards the city of Chasiv Yar in early April, a strategically important settlement west of Bakhmut, and by early July had captured its easternmost district. Another offensive in the direction of the city of Toretsk was launched on 18 June, with the goal of capturing the city, and according to Ukrainian military observer and spokesperson Nazar Voloshyn, flanking Chasiv Yar from the south. Russian forces advanced to expand the salient northwest of Avdiivka in July, and on 19 July, made a breakthrough allowing them to begin advancing towards the operationally significant city of Pokrovsk.

#### Ukrainian offensive into Russia

On 6 August 2024, Ukraine launched their first direct offensive into Russian territory, the largest of any pro-Ukrainian incursion since the invasion's inception, into the bordering Kursk Oblast. The main axis of the initial advance centred in the direction of the town of Sudzha, located 10 kilometres (6.2 mi) from the border, which was reported by President Zelenskyy to have been captured on 15 August. Ukraine, taking advantage of the lack of experienced units and defences along the border with Kursk Oblast, was able to quickly seize territory in the opening days of the incursion. The incursion caused Russia to divert thousands of troops from occupied Ukrainian territory to counter the threat, though not from Donetsk Oblast.
Despite repeated deadlines set by Putin to push out Ukrainian troops, Russian forces had still not yet done so by the end of January 2025, with advances in Donetsk Oblast being prioritized over the Kursk salient. However, by February 2025, Russian forces in Donetsk Oblast were described by the ISW as not being fully protected from the theater-wide impacts of the incursion, with troops, armored vehicles, artillery, and air defense systems being pulled away from Ukrainian sectors to reinforce the Russian forces in Kursk.

#### Late 2024 and early 2025 Russian advances

Russian troops continued advancing in eastern Ukraine, notably at a faster pace than prior to the Kursk offensive, including towards the strategically important city of Pokrovsk, where their number of forces had instead been increased.
In late August 2024, Russian forces seized the city of Novohrodivka, southeast of Pokrovsk, bringing them within 8 kilometres of the city, while capturing Krasnohorivka and Ukrainsk, near Pokrovsk and west of Donetsk city, in early September. In late September, a Russian assault on the long-held city of Vuhledar began, leading to its fall on 1 October. Ukraine's 72nd Mechanised Brigade had defended the city for over two years, and said that the Russians had suffered "numerous losses" as they stormed the elevated city. Following the Russian capture, the city with a pre-war population of about 14,000 was described as a "sprawling ruin".
On 30 October, Ukrainian Major General Dmytro Marchenko was reported to have said "our front has crumbled" due to a dwindling ammunition supply, problems with military recruitment, and poor leadership. He said Zelensky's victory plan was too heavily focused on seeking more Western support. Briefings from Western officials had also become more pessimistic about Ukraine's military situation. According to the Prosecutor General's Office, more than 100,000 criminal cases for desertion were initiated by the end of November 2024.
In early 2025, Russian forces advanced in eastern Ukraine. Russia continued attacks on the Ukrainian energy infrastructure. In February 2025, Ukraine's government approved a one-year contract for volunteers aged 18–24 who are currently not subject to mobilization.

## Battlespaces
### Command

The supreme commanders-in-chief are the heads of state of the respective governments: President Vladimir Putin of Russia and President Volodymyr Zelenskyy of Ukraine. Putin has reportedly meddled in operational decisions, bypassing senior commanders and giving orders directly to brigade commanders.
US general Mark Milley said that Ukraine's top military commander in the war, commander-in-chief of the Armed Forces of Ukraine, General Valerii Zaluzhnyi, "has emerged as the military mind his country needed. His leadership enabled the Ukrainian armed forces to adapt quickly with battlefield initiative against the Russians." Russia began the invasion with no overall commander. The commanders of the four military districts were each responsible for their own offensives.
After initial setbacks, the commander of the Russian Southern Military District, Aleksandr Dvornikov, was placed in overall command on 8 April 2022, while still responsible for his own campaign. Russian forces benefited from the centralisation of command under Dvornikov, but continued failures to meet expectations in Moscow led to multiple changes in overall command:
* commander of the Eastern Military District Gennady Zhidko (Eastern Military District, 26 – 8 May October 2022)
* commander of the southern grouping of forces Sergei Surovikin (early October 2022 – 11 January 2023)
* commander-in-chief of the Russian Armed Forces Valerii Gerasimov (from 11 January 2023)
Russia has suffered a remarkably large number of casualties in the ranks of its officers, including 12 generals.

### Missile attacks and aerial warfare

Aerial warfare began the first day of the invasion. Dozens of missile attacks were recorded across both eastern and western Ukraine, reaching as far west as Lviv.
By September 2022, the Ukrainian air force had shot down about 55 Russian warplanes. In mid-October, Russian forces launched missile strikes against Ukrainian infrastructure, intended to knock out energy facilities. By late November, hundreds of civilians had been killed or wounded in the attacks, and rolling blackouts had left millions without power.
In December 2022, drones launched from Ukraine allegedly carried out several attacks on Dyagilevo and Engels air bases in western Russia, killing 10 and heavily damaging two Tu-95 aircraft.

#### Crimea attacks

On 31 July 2022, Russian Navy Day commemorations were cancelled after a drone attack reportedly wounded several people at the Russian Black Sea Fleet headquarters in Sevastopol. On 9 August 2022, large explosions were reported at Saky Air Base in western Crimea. Satellite imagery showed at least eight aircraft damaged or destroyed. Initial speculation attributed the explosions to long-range missiles, sabotage by special forces or an accident; Ukrainian general Valerii Zaluzhnyi claimed responsibility on 7 September.
The base is near Novofedorivka, a destination popular with tourists. Traffic backed up at the Crimean Bridge after the explosions with queues of civilians trying to leave the area. A week later Russia blamed "sabotage" for explosions and a fire at an arms depot near Dzhankoi in northeastern Crimea that also damaged a railway line and power station. Russian regional head Sergei Aksyonov said that 2,000 people were evacuated from the area. On 18 August, explosions were reported at Belbek Air Base north of Sevastopol. On the morning of 8 October 2022 the Kerch Bridge, linking occupied Crimea to Russia, partially collapsed due to an explosion. On 17 July 2023, there was another large explosion on the bridge.

#### Russian attacks against Ukrainian civilian infrastructure

Since fall of 2022, Russia has carried out waves of strikes on Ukrainian electrical and water systems. On 6 October the Ukrainian military reported that 86 Shahed 136 kamikaze drones had been launched by Russian forces in total, and between 30 September and 6 October Ukrainian forces had destroyed 24 out of 46 launched in that period. On 8 October, it was announced that General of the Army Sergey Surovikin would be commanding all Russian forces in Ukraine on the strength of his novel air assault technique.
On 16 October 2022, The Washington Post reported that Iran was planning to supply Russia with both drones and missiles. On 18 October the US State Department accused Iran of violating Resolution 2231 by selling Shahed 131 and Shahed 136 drones to Russia, agreeing with similar assessments by France and the United Kingdom. Iran denied sending any arms to Russia for the Ukraine war. On 22 October France, Britain and Germany formally called for a UN investigation. On 1 November, CNN reported that Iran was preparing to send ballistic missiles and other weapons to Russia for use in Ukraine.
On 15 November 2022, Russia fired 85 missiles at the Ukrainian power grid, causing major power outages in Kyiv and neighboring regions.
On 21 November, CNN quoted an intelligence assessment that Iran had begun to help Russia produce Iran-designed drones in Russia.
On 31 December, Putin in his New Year address called the war against Ukraine a "sacred duty to our ancestors and descendants" as missiles and drones rained down on Kyiv.
On 10 March 2023, The New York Times reported that Russia had used new hypersonic missiles in a massive missile attack on Ukraine. Such missiles are more effective in evading conventional Ukrainian anti-missile defences that had previously proved useful against Russia's conventional, non-hypersonic missile systems.
The strikes against Ukrainian infrastructure were part of Russia's 'Strategic Operation for the Destruction of Critically Important Targets' (SODCIT) military doctrine, said the UK Defence Ministry, intended to demoralise the population and forcing the Ukrainian leadership to capitulate. According to the Royal United Services Institute (RUSI),
   Russian strikes had cumulatively destroyed 9 gigawatts (GW) of Ukraine's domestic power generation by mid-June 2024. Peak consumption during the winter of 2023 was 18 GW, which means that half of Ukraine's production capacity has been destroyed.
On 8 July 2024, Russia used a Kh-101 missile to kill at least two people and injure at least 16 people at the Okhmatdyt Children's Hospital in Kyiv. Also hit the same night were facilities in Pokrovsk and Kryvyi Rih. At least 20 civilians were killed in Kyiv that night.

### Naval blockade and engagements

Ukraine lies on the Black Sea, which has ocean access only through the Turkish-held Bosphorus and Dardanelles straits. On 28 February 2022, Turkey invoked the 1936 Montreux Convention and sealed off the straits to Russian warships that were not registered to Black Sea home bases and returning to their ports of origin. It specifically denied passage through the Turkish Straits to four Russian naval vessels. On 24 February, the State Border Guard Service of Ukraine announced that Russian Navy ships had begun an attack on Snake Island. The guided missile cruiser Moskva and patrol boat Vasily Bykov bombarded the island with deck guns. The Russian warship identified itself and instructed the Ukrainians on the island to surrender. Their response was "Russian warship, go fuck yourself!" After the bombardment, a detachment of Russian soldiers landed and took control of Snake Island. Russia said on 26 February that US drones had supplied intelligence to the Ukrainian navy to help it target Russian warships in the Black Sea. The US denied this.
By 3 March, Ukrainian forces in Mykolaiv scuttled the frigate Hetman Sahaidachny, the flagship of the Ukrainian navy, to prevent its capture by Russian forces. On 24 March, Ukrainian officials said that a Russian landing ship docked in Berdiansk—initially reported to be the Orsk and then its sister ship, the Saratov—was destroyed by a Ukrainian rocket attack. In March 2022, the UN International Maritime Organization (IMO) sought to create a safe sea corridor for commercial vessels to leave Ukrainian ports. On 27 March, Russia established a sea corridor 80 miles (130 km) long and 3 miles (4.8 km) wide through its Maritime Exclusion Zone, for the transit of merchant vessels from the edge of Ukrainian territorial waters southeast of Odesa. Ukraine closed its ports at MARSEC level 3, with sea mines laid in port approaches, pending the end of hostilities.
The Russian cruiser Moskva, the flagship of the Black Sea Fleet, was, according to Ukrainian sources and a US senior official, hit on 13 April by two Ukrainian Neptune anti-ship cruise missiles, setting the ship afire. The Russian Defence Ministry said the warship had suffered serious damage from a munition explosion caused by a fire, and that its entire crew had been evacuated. Pentagon spokesman John Kirby reported on 14 April that satellite images showed that the Russian warship had suffered a sizeable explosion onboard but was heading to the east for expected repairs and refitting in Sevastopol. Later the same day, the Russian Ministry of Defence stated that the Moskva had sunk while under tow in rough weather. On 15 April, Reuters reported that Russia launched an apparent retaliatory missile strike against the missile factory Luch Design Bureau in Kyiv where the Neptune missiles used in the Moskva attack were manufactured and designed. On 5 May, a US official confirmed that the US gave "a range of intelligence" (including real-time battlefield targeting intelligence) to assist in the sinking of the Moskva.
On 1 June, Russian Foreign Minister Sergey Lavrov asserted that Ukraine's policy of mining its own harbours to impede Russian maritime aggression had contributed to the food export crisis, saying: "If Kyiv solves the problem of demining ports, the Russian Navy will ensure the unimpeded passage of ships with grain to the Mediterranean Sea." On 30 June 2022, Russia announced that it had withdrawn its troops from the island in a "gesture of goodwill." The withdrawal was later confirmed by Ukraine.
On 26 December 2023, Ukraine's air force attacked the Russian landing ship Novocherkassk docked in Feodosia. Ukraine said it was destroyed—unlikely to sail again. Russian authorities confirmed the attack, but not the loss, and said two attacking aircraft were destroyed. Independent analysts said the ship's loss could hamper future Russian attacks on Ukraine's coast. On 31 January 2024, Ukrainian sea drones struck the Russian Tarantul-class corvette Ivanovets in the Black Sea, causing the ship to sink. Two weeks later on 14 February, the same type of Ukrainian sea drones struck and sank the Russian landing ship Tsezar Kunikov.

### Ukrainian resistance

Ukrainian civilians resisted the Russian invasion by volunteering for territorial defence units, making Molotov cocktails, donating food, building barriers like Czech hedgehogs, and helping to transport refugees. Responding to a call from Ukravtodor, Ukraine's transportation agency, civilians dismantled or altered road signs, constructed makeshift barriers, and blocked roadways. Social media reports showed spontaneous street protests against Russian forces in occupied settlements, often evolving into verbal altercations and physical standoffs with Russian troops. By the beginning of April, Ukrainian civilians began to organise as guerrillas, mostly in the wooded north and east of the country. The Ukrainian military announced plans for a large-scale guerrilla campaign to complement its conventional defence.
People physically blocked Russian military vehicles, sometimes forcing them to retreat. The Russian soldiers' response to unarmed civilian resistance varied from reluctance to engage the protesters, to firing into the air, to firing directly into crowds. There have been mass detentions of Ukrainian protesters, and Ukrainian media has reported forced disappearances, mock executions, hostage-taking, extrajudicial killings, and sexual violence perpetrated by the Russian military. To facilitate Ukrainian attacks, civilians reported Russian military positions via a Telegram chatbot and Diia, a Ukrainian government app previously used by citizens to upload official identity and medical documents. In response, Russian forces began destroying mobile phone network equipment, searching door-to-door for smartphones and computers, and in at least one case killed a civilian who had pictures of Russian tanks.
As of 21 May 2022, Zelenskyy indicated that Ukraine had 700,000 service members on active duty fighting the Russian invasion. Ukraine withdrew soldiers and military equipment back to Ukraine over the course of 2022 that had been deployed to United Nations peacekeeping missions like MONUSCO in the Democratic Republic of the Congo.

## Foreign involvement
### Support for Ukraine

In response to the invasion, many countries have supplied military aid to Ukraine including weaponry, equipment, training, and logistical support. Western and other countries imposed limited sanctions on Russia in the prelude to the invasion and applied new sanctions when the invasion began, intending to cripple the Russian economy; sanctions targeted individuals, banks, businesses, monetary exchanges, exports, and imports.
Military assistance has mostly been co-ordinated through the Ukraine Defence Contact Group, whose more than fifty countries include all 32 member states of NATO. From January 2022 to January 2024, $380 billion in aid to Ukraine was tracked by the Kiel Institute. European countries have provided the most aid in total (military, financial and humanitarian). Estonia and Denmark have provided the most military aid as a share of GDP. The European Union co-ordinated the supply of military aid for the first time. Meanwhile, the United States has provided the most military assistance to Ukraine, and has set aside $175 billion to help the country. Most of the US military aid has been old American weaponry and equipment from reserve stockpiles, while most of the US funding earmarked for Ukraine stays in the US economy and supports US industries, subsidizing the manufacture of weapons and military equipment. Bulgaria supplied Ukraine with over one third of the ammunition needed in the early phase of the invasion and a plurality of needed fuel.
Although India has maintained a neutral stance on the invasion, reports indicate that artillery shells made by Indian manufacturers were sold to European countries and then diverted to Ukraine. Indian officials have not intervened despite objections from Russia.
Most of Ukraine's supporters ruled out sending troops to the country in the early months of the invasion. President Emmanuel Macron of France later said in 2024 that sending troops was a possibility.
The Russian government has threatened retaliation against countries supplying military aid to Ukraine, and said it meant NATO was waging a "proxy war" against Russia. Russia's government has not followed through on its threats, despite most of its "red lines" being crossed. President Putin said that if military aid stopped, Ukraine would not survive for long.

### Support for Russia
#### Belarus

Belarus has allowed Russia to use its territory to stage part of the invasion, and to launch Russian missiles into Ukraine. Belarus airspace was used by Russia, including for radar early warning and control missions, until 2023, when a Russian Beriev A-50 surveillance plane was damaged by drones. Because of its active involvement, Belarus is considered a co-belligerent in this invasion, as contrasted to non-belligerent states, which have "a wide range of tools available to non-belligerent actors without reaching the threshold of warfighting". Political scientist Matthew Frear considers Belarus a co-combatant, with "Lukashenko repeatedly stated his support for Putin’s military actions", while 2023 issue of IISS's "Armed Conflict Survey" journal classified it as not a direct co-combatant. Belarus provided Russia with weapons and ammunition, and later, according to the 2024 issue of "Armed Conflict Survey", Russia deployed tactical nuclear weapons in Belarus.

#### Iran

In June 2023, US military intelligence suggested Iran was providing both Shahed combat drones and production materials to develop a drone manufactory to Russia. In February 2024, a Reuters report indicated that Iran sent ballistic missiles to the Russian military. According to the US and Ukraine, Iranian troops have been stationed in Crimea to assist Russia in launching drone attacks against civilians and civilian infrastructure. The Institute for the Study of War assessed that these are likely Islamic Revolutionary Guard Corps (IRGC) or IRGC-affiliated personnel. Iran has denied sending arms to Russia for use against Ukraine.

#### North Korea

North Korea has supplied Russia with ballistic missiles and launchers although US authorities did not mention the specific models. Based on debris left by missiles on 30 December 2023 attacks against Ukrainian targets show parts common to KN-23, KN-24 and KN-25 missiles. In October 2024, Ukraine and South Korea claimed that North Korean engineers had been deployed to the battlefield to help with the launch of these missiles, and had suffered some casualties.
Later the same month, a White House spokesperson said that the United States was "concerned" about reports that North Korean soldiers were fighting for Russia in Ukraine. A day later, Zelensky announced that Ukrainian intelligence believed there were 10,000 North Korean troops preparing to join Russian forces on the front line. The North Korean government rejected these claims and stated that none of their soldiers were fighting for Russia.
The US later said it had seen evidence that North Korea had sent 3,000 soldiers to Russia for possible deployment to Ukraine, determining that the soldiers had been transported from North Korea by ship in early-to-mid October and were undergoing training at three military bases in eastern Russia. The US added that the alleged North Korean deployment could be further evidence that the Russian military was having problems with manpower. On 28 October, NATO chief Mark Rutte confirmed earlier Ukrainian intelligence that North Korean troops had been deployed to Kursk Oblast to support Russia against the 2024 Kursk Offensive, and the Pentagon reported an increased number of 10,000 North Korean soldiers sent to train in Russia and fight in the war.
On 7 November, the Ukrainian defence minister reported that North Korean troops had been engaged in battle on 5 November. On 13 November, both the US State Department and South Korea confirmed that North Korean troops had begun engaging in combat against Ukrainian forces in Kursk Oblast. The Pentagon could not confirm the claims. On 24 November, the Ukrainian chief of general staff confirmed that North Korean troops have been engaged in battle. On 2 December the Pentagon stated that it has no evidence of North Korean troops engaged in combat, but noted that North Korean soldiers had been integrated into Russian units. A representative of the Ukrainian intelligence directorate confirmed that North Korean troops have been integrated into Russian units held in reserve but said that North Korean troops are unlikely to be engaged in combat on the front line and are still engaged in training. The presence of North Korean troops in Kursk is seen as enabling Russia in its fight against Ukraine. On 16 December, the US confirmed that North Korean troops had been killed and injured in combat in Russia's Kursk oblast. By 18 December, the number of killed and wounded North Korean soldiers had reportedly reached "a couple hundred", while South Korea reported 100 North Koreans dead and 1000 injured. Writing in December 2024 for the Lieber Institute's Articles of War publication, US Army JAG officers Steve Szymanski and Joshua C.T. Keruski stated that North Korea had become a party to an international armed conflict with Ukraine as of the 5 November 2024 engagement.
Zelenskyy also showcased footage which he said showed Russian troops burning the faces of killed North Korean soldiers in an attempt to conceal their presence on the battlefield.
In January 2025 two North Korean servicemen were taken prisoner while fighting in Kursk Oblast. Intelligence debriefings indicate that North Korean soldiers have been issued with false military papers stating that they are Russians hailing from Tuva.

#### Others

Politico reported in March 2023 that Chinese state-owned weapons manufacturer Norinco shipped assault rifles, drone parts, and body armor to Russia between June and December 2022, with some shipments via third countries including Turkey and the United Arab Emirates. According to the United States, Chinese ammunition has been used on battlefields in Ukraine. In May 2023, the European Union identified that Chinese and UAE firms were supplying weapon components to Russia. In April 2024, China was reported to have provided Russia with geospatial intelligence, machine tools for tanks, and propellants for missiles. In September 2024, Reuters reported documents indicating Russia had established a weapons programme in China to develop and produce long-range attack drones, with assistance from local specialists, for use in the invasion of Ukraine.
Russia imports sensitive electronics, machinery, auto parts, and defence equipment from India. Trade like oil sales has surged since 2022, boosting revenue for Russian state-owned companies. To bypass sanctions and manage its currency surplus, Russia pays in rupees, supporting both civilian and military needs.

## Casualties

Russian and Ukrainian sources have both been said to inflate the casualty numbers for opposing forces and downplay their own losses for the sake of morale. Leaked US documents say that "under-reporting of casualties within the [Russian] system highlights the military's 'continuing reluctance' to convey bad news up the chain of command." Russian news outlets have largely stopped reporting the Russian death toll. Russia and Ukraine have admitted suffering "significant" and "considerable" losses, respectively.
The numbers of civilian and military deaths have been as always impossible to determine precisely. Agence France-Presse (AFP) reported that neither it nor independent conflict monitors were able to verify Russian and Ukrainian claims of enemy losses and suspected that they were inflated. On 12 October 2022, the independent Russian media project iStories, citing sources close to the Kremlin, reported that more than 90,000 Russian soldiers had been killed, seriously wounded, or gone missing in Ukraine.
While combat deaths can be inferred from a variety of sources, including satellite imagery of military action, measuring civilian deaths can be more difficult. On 16 June 2022, the Ukrainian Minister of Defence told CNN that he believed that tens of thousands of Ukrainians had died, adding that he hoped the total death toll was below 100,000. By the end of June 2024, about 20,000 Ukrainians had lost limbs. In the destroyed city of Mariupol alone, Ukrainian officials believe that at least 25,000 have been killed, and bodies were still being discovered in September 2022. The mayor said over 10,000 and possibly as many as 20,000 civilians died in the siege of Mariupol and that Russian forces had brought mobile cremation equipment with them when they entered the city. Researcher Dan Ciuriak from C. D. Howe Institute in August 2022 estimates the number of killed Mariupol civilians at 25,000, and an investigation by AP from the end of 2022 gives a number of up to 75,000 killed civilians in Mariupol area alone. AFP says that "a key gap in casualty counts is the lack of information from Russian-occupied places like the port city of Mariupol, where tens of thousands of civilians are believed to have died". According to a study by Human Rights Watch and two other organisations, there were at least 8,034 excess deaths in Mariupol between March 2022 and February 2023. The Office of the United Nations High Commissioner for Human Rights (OHCHR) reports similar issues and believed that the true civilian casualty numbers were significantly higher than it has been able to confirm.
In the Russian military during the invasion, Russia's ethnic minorities have been suffering disproportionately high casualties. In October 2022, the Russian regions with the highest death tolls were Dagestan, Tuva and Buryatia, all minority regions. In February 2024, six out of ten Russian regions with the highest mortality rates in Ukraine were located in Siberia and the far east, and ethnic minorities continuing outsized casualty rates prompted analysts to warn that the situation will lead to long-term destructive impacts on these communities. According to Western officials, about 1,200 Russian soldiers were killed or wounded in Ukraine every day in May and June 2024, which climbed to 1,500 killed or wounded daily by November 2024, when 45,690 casualties were estimated that month. Newsweek estimated that on the bloodiest day in November 2024 the ratio of killed Russian men (1,950) exceeded the average daily male birth rate in Russia (1,836). Latvia-based news outlet Meduza estimated that up to 140,000 Russian soldiers had died in the war by the end of June 2024.
The Russian invasion became the deadliest European war in the last 80 years, surpassing the death toll of the Bosnian War. Ukrainian average mortality rate was 8.7/1000 people in 2020, and jumped to 18.6/1000 in 2024, whereas Russia's mortality rate that same year was 14/1000, ranking them as #1 and #9, respectively, on the list of countries with the highest mortality rates. In August 2024, Haaretz estimated 172,000 people had died in the Russian invasion of Ukraine. In February 2025, Quincy Institute for Responsible Statecraft estimated 250,000 dead. In September 2024, the Wall Street Journal reported that there were now one million Ukrainians and Russians who were killed or wounded. The Journal took note of how the number of casualties impacts the two countries' shrinking prewar populations.

## War crimes and attacks on civilians

During the invasion, the Russian military and authorities have been responsible for deliberate attacks against civilian targets (including strikes on hospitals and on the energy grid), massacres of civilians, abduction and torture of civilians, sexual violence, forced deportation of civilians, and torture and murder of Ukrainian prisoners of war. They have also carried out many indiscriminate attacks in densely populated areas, including with cluster bombs, in once instance killing 61 people in the Kramatorsk railway station attack. According to Kyrylo Budanov, the chief of the Ukrainian intelligence, Russia before the start of the invasion of Ukraine had created 'execution lists' of Ukrainian teachers, journalists, scientists, writers, priests, politicians and was preparing for a genocide of Ukrainians, also the plans included locations of mass graves and mobile crematoriums.
According to the Office of the United Nations High Commissioner for Human Rights, by December 2023, about 78% of confirmed civilian casualties had been killed in Ukrainian-controlled territory, while 21% had been killed in Russian-occupied territory. Over 12,300 civilians have been killed since the start of the invasion. Russia has deliberately targeted Ukrainian civilians with drones, such as in the Kherson terror campaign dubbed the human safari. A representative from the Kherson military administration said nearly half of the 547 casualties reported from 1 July to 9 September 2024 were caused by drones.
The UN Human Rights Office reports that Russia is committing severe human rights violations in occupied Ukraine, including arbitrary detentions, enforced disappearances, torture, crackdown on protests and freedom of speech, enforced Russification, indoctrination of children, and suppression of Ukrainian language and culture. Ukrainians have been coerced into taking Russian passports and becoming Russian citizens. Those who refuse are denied healthcare and other rights, and can be imprisoned as a "foreign citizen". Ukrainian men who take Russian citizenship are drafted to fight against the Ukrainian army.
Russian forces have reportedly used banned chemical weapons during the war, usually tear gas grenades. In April 2024, a Daily Telegraph investigation concluded that "Russian troops are carrying out a systematic campaign of illegal chemical attacks against Ukrainian soldiers".

### Prisoners of war

A 25 August 2022 report by the Humanitarian Research Lab of the Yale School of Public Health identified some 21 filtration camps for Ukrainian "civilians, POWs, and other personnel" in the vicinity of Donetsk oblast. Imaging of one camp, Olenivka prison, found two sites featuring disturbed earth consistent with "potential graves." Kaveh Khoshnood, a professor at the Yale School of Public Health, said: "Incommunicado detention of civilians is more than a violation of international humanitarian law—it represents a threat to the public health of those currently in the custody of Russia and its proxies." Conditions described by freed prisoners include exposure, insufficient access to sanitation, food and water, cramped conditions, electrical shocks and physical assault.
An OHCHR report released in November 2022 documented abuses on both sides. The report was based on interviews with prisoners who spoke of abuses and ill-treatment.
In March 2023, UN human rights commissioner Volker Türk reported that more than 90% of the Ukrainian POWs interviewed by his office said they had been tortured or ill-treated, including ″welcoming beatings″ on their arrival in penitentiary facilities, which Russia despite several requests did not give UN staff access to.
In April 2023, several videos started circulating on different websites purportedly showing Russian soldiers beheading Ukrainian soldiers.
In March 2024, the United Nations issued a report saying Russia may have executed more than 30 recently captured Ukrainian prisoners of war over the winter months. The UN Human Rights Office verified three incidents in which Russian servicemen executed seven Ukrainian servicemen. According to the same report, 39 of 60 released Ukrainian prisoners of war also "disclosed that they had been subjected to sexual violence during their internment, including attempted rape, threats of rape and castration, beatings or the administration of electric shocks to genitals, and repeated forced nudity, including during interrogations and to check for tattoos".
In October 2024, the EEAS released a statement describing the increasing frequency of Russian executions of Ukrainian prisoners, with at least 177 prisoners dying in Russian captivity since the beginning of the war. The statement also included the Office of the United Nations High Commissioner for Human Rights (OHCHR)'s confirmation of systematic use of a wide range of different methods of torture used by Russians against Ukrainian prisoners.
The Ukrainian Armed Forces have also been accused of executions and other abuses of Russian prisoners of war, but the number of such allegations has been significantly lower.$^{:para.105}$

### Abduction of Ukrainian children

In June 2024, an investigation by the Financial Times identified four Ukrainian children on a Russian government-linked adoption website that had been abducted from state care homes. The children's Ukrainian background was not mentioned. One child was shown with a new Russian name and age that differed from their Ukrainian documents, another was shown using a Russian version of their Ukrainian name. 17 other matches identified by the Financial Times on the adoption website were also confirmed as Ukrainian children in a recent New York Times investigation. Ukrainian authorities estimate that nearly 20,000 Ukrainian children have been forcibly taken from occupied territories to Russia since the full-scale invasion began. Wayne Jordash, president of humanitarian law firm Global Rights Compliance, described forcibly transferring or deporting children as war crimes, adding that when done as part of a widespread or systematic attack on a civilian population, Russia is also committing crimes against humanity.

### International arrest warrants

The International Criminal Court (ICC) opened an investigation into possible crimes against humanity, genocide and war crimes committed in Ukraine. On 17 March 2023, the ICC issued a warrant for Putin's arrest, charging him with individual criminal responsibility in the abduction of children forcibly deported to Russia. It was the first time that the ICC had issued an arrest warrant for the head of state of a permanent member of the United Nations Security Council (the world's five principal nuclear powers). Moscow has denied any involvement in war crimes, a response Vittorio Bufacchi of University College Cork says "has bordered on the farcical," and its contention that the images coming out of Bucha were fabricated "a disingenuous response born by delusional hubris, post-truth on overdrive, (that) does not merit to be taken seriously." Even the usually fractured United States Senate came together to call Putin a war criminal.
One of several efforts to document Russian war crimes concerns its repeated bombardment of markets and bread lines, destruction of basic infrastructure and attacks on exports and supply convoys, in a country where deliberate starvation of Ukrainians by Soviets the Holodomor still looms large in public memory. Forcible deportation of populations, such as took place in Mariupol, is another area of focus, since,
   forced deportations and transfers are defined both as war crimes under the Fourth Geneva Convention and Protocol II and Article 8 of the Rome Statute—and as crimes against humanity—under Article 7 of the Rome Statute. As both war crimes and crimes against humanity, they have several mechanisms for individual accountability, the International Criminal Court and also, at the individual state level, universal jurisdiction and Magnitsky sanctions legislation.
The ICC also issued arrest warrants for military officials Sergey Kobylash, Viktor Sokolov, Sergei Shoigu and Valery Gerasimov.

## Impacts
### Humanitarian impact

The humanitarian impact of the invasion has been extensive and has included negative impacts on international food supplies and the 2022 food crises. An estimated 6.6 million Ukrainians were internally displaced by August 2022, and about the same number were refugees in other countries. The invasion has devastated the cultural heritage of Ukraine, with over 500 Ukrainian cultural heritage sites, including cultural centres, theatres, museums, and churches, affected by "Russian aggression." Ukraine's Minister of Culture Oleksandr Tkachenko called it cultural genocide. Deliberate destruction and looting of Ukrainian cultural heritage sites in this way is considered a war crime.
The Russian attacks on civilians, causing mass civilian casualties and displacement, have been characterised as genocide and democide. On 15 September 2023, a UN-mandated investigative body presented their findings that Russian occupiers had tortured Ukrainians so brutally that some of their victims died, and forced families to listen as they raped women next door. The commission has previously said that violations committed by Russian forces in Ukraine, including the use of torture, may constitute crimes against humanity.
A report by Physicians for Human Rights described Russian violence against the Ukrainian health care system as being a prominent feature of Russia's conduct during the war, documenting 707 attacks on Ukraine's health care system between 24 February and 31 December 2022. Such attacks are considered war crimes.

### Refugee crisis

The war caused the largest refugee and humanitarian crisis in Europe since the Yugoslav Wars in the 1990s; the UN described it as the fastest growing such crisis since World War II. As Russia built up military forces along the Ukrainian border, many neighbouring governments and aid organisations prepared for a mass displacement event in the weeks before the invasion. In December 2021, the Ukrainian defence minister estimated that an invasion could force three to five million people to flee their homes.
In the first week of the invasion, the UN reported over a million refugees had fled Ukraine; this subsequently reached over eight million by 31 January 2023. On 20 May 2022, NPR reported that, following a significant influx of foreign military equipment into Ukraine, a significant number of refugees were seeking to return to regions in Ukraine which were relatively isolated from the invasion front in southeastern Ukraine. By 3 May, another 8 million people were displaced inside Ukraine.
Most refugees were women, children, elderly, or disabled. Most male Ukrainian nationals aged 18 to 60 were denied exit from Ukraine as part of mandatory conscription, unless they were responsible for the financial support of three or more children, single fathers, or were the parent/guardian of children with disabilities. Many Ukrainian men, including teenagers, opted to remain in Ukraine voluntarily to join the resistance.
According to the UN High Commission for Refugees as of 13 May 2022, there were 3,315,711 refugees in Poland, 901,696 in Romania, 594,664 in Hungary, 461,742 in Moldova, 415,402 in Slovakia, and 27,308 in Belarus, while Russia reported it had received over 800,104 refugees. By 13 July 2022, over 390,000 Ukrainian refugees had arrived in the Czech Republic, where the average refugee was a woman accompanied by one child. These refugees were twice as likely to have a college degree as the Czech population as a whole. Turkey has been another significant destination, registering more than 58,000 Ukrainian refugees as of 22 March 2022. The EU invoked the Temporary Protection Directive for the first time in its history, granting Ukrainian refugees the right to live and work in the EU for up to three years. Britain has accepted 146,379 refugees, as well as extending the ability to remain in the UK for three years with broadly similar entitlements as the EU, three years residency and access to state welfare and services.
According to the Organization for Security and Co-operation in Europe (OSCE), Russia has engaged in "massive deportation" of over 1.3 million Ukrainian civilians, potentially constituting crimes against humanity. The OSCE and Ukraine have accused Russia of forcibly moving civilians to filtration camps in Russian-held territory, and then into Russia. Ukrainian sources have compared this policy to Soviet-era population transfers and Russian actions in the Chechen War of Independence. For instance, as of 8 April 2022, Russia claimed to have evacuated about 121,000 Mariupol residents to Russia. Also, on 19 October, Russia announced the forced deportation of 60,000 civilians from areas around the line of contact in Kherson oblast. RIA Novosti and Ukrainian officials said that thousands were dispatched to various centres in cities in Russia and Russian-occupied Ukraine, from which people were sent to economically depressed regions of Russia. In April, Ukraine's National Security and Defence Council secretary Oleksiy Danilov said that Russia planned to build "concentration camps" for Ukrainians in western Siberia, and likely planned to force prisoners to build new cities in Siberia.

### Long-term demographic effects

Both Russia and Ukraine faced the prospect of significant population decline even before the war, having among the lowest fertility rates worldwide and considerable emigration. It is the first time that two countries with an average age above 40 have gone to war against each other. Russia had a fighting-age (18-to-40-year-old) male population more than four times higher than Ukraine's and slightly higher birth rates, while the willingness to fight was more pronounced in Ukraine.
Several sources have pointed out that the war is considerably worsening Ukraine's demographic crisis, making significant shrinking very likely. A July 2023 study by the Vienna Institute for International Economic Studies stated that,
   regardless of how long the war lasts and whether or not there is further military escalation, Ukraine is unlikely to recover demographically from the consequences of the war. Even in 2040 it will have only about 35 million inhabitants, around 20% fewer than before the war (2021: 42.8 million) and the decline in the working-age population is likely to be the most severe and far-reaching.
The study took different scenarios, from a "best case" (end of the war in 2023 without much further escalation) to a "worst case" (end of the war in 2025 with further escalation) into account. Flight from war affected especially the southern and eastern regions and especially educated women of child-bearing age and their children. With an estimate of more than 20% of refugees not returning, study author Maryna Tverdostup concluded that long-term shrinking will significantly impair the conditions for reconstruction.
The war in Ukraine and the associated emigration, lower birth rates and war-related casualties further deepened the demographic crisis of Russia. Many commentators predict that the situation will be worse than during the 1990s. The UN is projecting that the decline that started in 2021 will continue, and if current demographic conditions persist, Russia's population would be 120 million in fifty years, a decline of about 17%.
Since February 2022, hundreds of thousands of Russians have emigrated; estimates range from 370,000 to over 820,000. Combined with mobilisation, this possibly removed roughly half a million to one million working-age males from Russia's population. Studies report that this will have a demographic effect, especially in Russia, that lasts much longer than the conflict, and Putin's time in office.
According to BBC:
   They come from different walks of life. Some are journalists like us, but there are also IT experts, designers, artists, academics, lawyers, doctors, PR specialists, and linguists. Most are under 50. Many share western liberal values and hope Russia will be a democratic country one day. Some are LGBTQ+. Sociologists studying the current Russian emigration say there is evidence that those leaving are younger, better educated and wealthier than those staying. More often they are from bigger cities.
According to Johannes Wachs, "The exodus of skilled human capital, sometimes called brain drain, out of Russia may have a significant effect on the course of the war and the Russian economy in the long run." According to a survey, around 15 percent of those who left returned to Russia, either permanently or to settle their affairs.
In November 2023, at the World Russian People's Council, Putin urged Russian women to have eight or more children amid increasing Russian casualties in the invasion.
In July 2024, Chief of the General Staff of the British Army Roland Walker said that with the current way of fighting, it would take Russia five years to control the four oblasts of Donetsk, Luhansk, Kherson and Zaporizhzhia that Russia claims as its own, and it would cost Russia from 1.5 to 1.8 million casualties. He said there are "no winners" in Russia's invasion, adding "it is an utter devastation for both sides and lost generations."

### Environmental impact

Based on a preliminary assessment, the war has inflicted $51 billion in environmental damage in Ukraine; according to a report by the Yale School of the Environment, some 623,000 tonnes (1.4 billion pounds) of petrochemicals have burned as a result of shelling, while nearly 1,500 tonnes (3.2 million pounds) of pollutants have leaked into bodies of water. Hazardous chemicals have contaminated around 28 hectares (70 acres) of soil, and likely made agricultural activities temporarily impossible. Around 30% of Ukraine's land is now littered with explosives and more than 2.4 million hectares (5.9 million acres) of forest have been damaged.
According to Netherlands-based peace organisation PAX, Russia's "deliberate targeting of industrial and energy infrastructure" has caused "severe" pollution, and the use of explosive weapons has left "millions of tonnes" of contaminated debris in cities and towns. In early June 2023, the Kakhovka Dam, under Russian occupation, was damaged, causing flooding and triggering warnings of an "ecological disaster."
The Ukrainian government, international observers and journalists have described the damage as ecocide. The Ukrainian government is investigating more crimes against the environment and ecocide (a crime in Ukraine). Zelenskyy has met with prominent European figures (Heidi Hautala, Margot Wallstrom, Mary Robinson and Greta Thunberg) to discuss the environmental damage and how to prosecute it.
According to an investigation by NGL Media published in April 2024, Russia has completely destroyed over 60,000 hectares (150,000 acres) of Ukrainian forests. The investigation stated that long-term ecological consequences may include lowering of the groundwater level, reduction of biodiversity, worsening of air quality, fire outbreaks, and rivers and ponds drying up.
The war has severely disrupted climate policy all over the world and increased CO2 emissions. The effects have been strongly felt in Asia, Europe, and the US. Fatih Birol, the head of the International Energy Agency talking about the prospects of COP 28 noted:
   ... the geopolitical situation, with many nations at loggerheads over the war in Ukraine, and still frosty relations between the US and China, would make for a difficult summit. [...] The most important challenge [to limiting temperature rises to 1.5 °C (2.7 °F) above pre-industrial levels] is the lack of international cooperation.

### Nuclear risk

Senior Russian politicians—including Putin, Sergey Lavrov, and Dmitry Medvedev—have made statements widely seen as nuclear blackmail. They have implied that Russia may use nuclear weapons if certain "red lines" are crossed, such as helping Ukraine to strike back at Russia itself.
Four days into the invasion, Putin put Russia's nuclear forces on high alert, raising fears that Russia could use tactical nuclear weapons against Ukraine. In April, Putin "seemed to hint at the use of nuclear weapons against any nation that directly intervenes", and Sergei Lavrov said there was a "real" danger of a third world war. CIA director William Burns said that "desperation" in the face of defeat could lead Putin to order a nuclear strike. In September, the United States warned Russia's government that the country would suffer "catastrophic" consequences if it used nuclear weapons against Ukraine. Addressing the United Nations, President Biden accused Putin of making "overt, reckless and irresponsible" nuclear threats and said Russia would not win a nuclear war: "A nuclear war cannot be won and must never be fought". In March 2023, Putin announced plans to install Russian tactical nuclear weapons in Belarus.
By 2024, most of the Russian government's "red lines" had been crossed without nuclear weapons being used in response.
The invasion had an impact on Ukraine's nuclear power plants. Russian forces seized Chernobyl on the first day, leading to a huge spike in radiation levels. Russia also seized Zaporizhzhia Nuclear Power Plant, the largest in Europe. The plant has been damaged by shelling, Russian military equipment has been placed there, and safety protocols have been breached, leading to a nuclear safety crisis. Ukraine described the crisis as nuclear terrorism by Russia. In response to what he called "completely irresponsible actions", Zelenskyy suggested that there should be outside control over Russia's nuclear plants. The International Atomic Energy Agency (IAEA) issued stark warnings and said it was the first time a military conflict occurred amid nuclear plants. It called for a demilitarised zone around Zaporizhzhia NPP.

### Economic impact
#### Ukraine

Ukrainian Minister of Economic Development and Trade Yulia Svyrydenko announced that for 2022 Ukraine had a 30.4% loss in their GDP. The International Monetary Fund predicted that Ukraine's gross domestic product (GDP) would suffer a decrease from a minimum of 10% to a maximum of 35%; the European Bank for Reconstruction and Development also predicted that the invasion would cause a 20% decrease of Ukraine's GDP. The Ukrainian statistics service said that the GDP of Ukraine in 2023 grew by 5.3%.
Ukraine began issuing war bonds on 1 March 2022, and the following day the Ukrainian government announced that they had raised 6.14 billion hryvnias. A ban was placed in May 2022 by the European Commission on grain sales in the countries of: Bulgaria, Poland, Hungary, Romania and Slovakia with the only exception being if they were transiting through those countries with the ban being lifted in September 2023.
The war has caused a major humanitarian crisis in Ukraine: the United Nations Development Programme calculated in March 2022 that a prolonged conflict would cause 30% of the Ukrainian population to fall below the poverty line, while a further 62% would be at risk of also falling into poverty within a year.

#### Russia

The Russian economic ministry said that for 2022 the GDP contracted by 2.1% and for 2023 Russia's government said the GDP grew by 3.6%.
A price cap was placed on Russian oil by the Group of 7 (G7) at $60 on 5 December 2022. The United States banned all imports of Russian oil on 8 March 2022. The European Union placed an embargo on oil products from Russia on 5 February 2023. Other countries that embargoed Russian oil included Five Eyes partners Canada, the United Kingdom, Australia and New Zealand. Russia itself issued a ban on foreign diesel sales starting on 21 September 2023, before being lifted on 6 October.
On 27 April 2024, it was reported that Russia was planning increases in personal income taxes and corporate taxes to help pay for the war.
In January 2025, it was reported that, since early 2022, Russia had used a two-prong strategy to finance the extremely large costs of the war. In addition to the official Russian government defense budget —direct financial expenditure for waging the war in Ukraine was estimated at US$250 billion through June 2024 for military spending through normal channels, with the military budget rising to over 20% of annual GDP—an additional off-budget financing mechanism was employed to fund the war with over US$200 billion of debt funding obtained from preferential bank loans made to defence contractors and war-related businesses, loans that had been compelled by the Russian government.

## Peace efforts

Peace negotiations between Russia and Ukraine took place on 28 February, 3 March, and 7 March 2022, on the Belarus–Ukraine border, with further talks held on 10 March in Turkey and a fourth round of negotiations beginning 14 March. The talks ended without agreement.
As of 2025, Ukraine's main peace terms are that Russia withdraw its troops, that Ukrainian prisoners be released, that Russian leaders be prosecuted for war crimes, and that Ukraine be given security guarantees to prevent further aggression. Russia's main terms are that Russia must keep all the land it occupies, that it also be given all of the provinces that it claims but does not fully control, that Ukraine end plans to join NATO, and that sanctions against Russia be lifted.
Several Western-based analysts say that allowing Russia to keep the land it seized would "reward the aggressor while punishing the victim" and set a dangerous precedent. They predict that this would allow Russia to re-arm and encourage it "to continue its imperialist campaign of expansionism" against Ukraine and its other neighbors, and embolden other expansionist regimes.
After Donald Trump became US president in 2025, there was a major shift in US policy. The Trump administration began negotiations with Russia and separately with Ukraine.

## International reactions

The invasion received widespread international condemnation from governments and intergovernmental organisations. On 2 March 2022 and on 23 February 2023, 141 member states of the UN General Assembly voted for a resolution saying that Russia should immediately withdraw. Seven, including Russia, voted against the measure. Political reactions to the invasion included new sanctions imposed on Russia, which triggered widespread economic effects on the Russian and world economies. Sanctions forced Russia to reorient its oil exports to non-sanctioning countries such as India, rely more on LNG (which was not subject to European Union sanctions), and shift its coal exports from Europe to Asia. Most European countries cancelled nuclear cooperation with Russia.
Over seventy sovereign states and the European Union delivered humanitarian aid to Ukraine, and nearly fifty countries plus the EU provided military aid. Economic sanctions included a ban on Russian aircraft using EU airspace, a ban of certain Russian banks from the SWIFT international payments system, and a ban on certain Russian media outlets. Reactions to the invasion have included public response, media responses, peace efforts, and the examination of the legal implications of the invasion.
Some countries, particularly in the Global South, saw public sympathy or outright support for Russia, due in part to distrust of US foreign policy. Protests and demonstrations were held worldwide, including some in Russia and parts of Ukraine occupied by Russia. Calls for a boycott of Russian goods spread on social media platforms, while hackers attacked Russian websites, particularly those operated by the Russian government. Anti-Russian sentiment against Russians living abroad surged after the invasion. In March 2022, Russian President Putin introduced prison sentences of up to 15 years for publishing "fake news" about Russian military operations, intended to suppress any criticism related to the war.
According to the Economist Intelligence Unit in 2023, 31 percent of the world's population live in countries that are leaning towards or supportive of Russia, 30.7 percent live in neutral countries, and 36.2 percent live in countries that are against Russia in some way.
A number of supranational and national parliaments passed resolutions declaring Russia to be a state sponsor of terrorism. By October 2022, three countries—Latvia, Lithuania and Estonia—had declared Russia a terrorist state. On 1 August 2023, Iceland became the first European country to close its embassy in Russia as a result of the invasion of Ukraine.
The invasion prompted Ukraine, Finland and Sweden to officially apply for NATO membership. Finland became a member of NATO on 4 April 2023, followed by Sweden on 7 March 2024.
A documentary film produced during the siege of Mariupol, 20 Days in Mariupol, won the Oscar for best documentary in 2024.
