UK applauds Ukraine’s heroic resistance and demands Russia end its illegal war: UK Statement to the OSCE

UK Military Advisor, Lt Col Joby Rimmer, reiterates the UK's call for Russia to cease its unlawful aggression against Ukraine and reaffirms Ukraine’s right to self-defence under international law.

Thank you, Madame Chair. The United Kingdom again calls on the Russian Federation to immediately cease its illegal and unprovoked aggression against Ukraine. Prime Minister Keir Starmer has been extremely clear: Ukraine is not defeated. On the contrary, it has emerged as a formidable fighting force, demonstrating extraordinary resilience and determination in defending its sovereignty. And let us be clear, Ukraine has an absolute right to defend itself against aggression, and the United Kingdom stands firmly in support of that right.

We remain focused on achieving a just and lasting peace. In Istanbul, Ukraine demonstrated its commitment to peace by offering reasonable and practical proposals aimed at securing an unconditional ceasefire. Regrettably, Russia failed to reciprocate. Instead, it presented maximalist, non-negotiable demands that do not respect Ukraine’s sovereignty. This behaviour underscores that President Putin is not serious about peace and remains committed to prolonging his illegal war.

Since Ukraine’s offer of a full, unconditional ceasefire on 11 March 2025, Russia has continued its brutal campaign, launching daily airstrikes that have killed over 500 civilians and injured more than 2,700. We fully anticipate that the Russian Federation will deliver more disinformation in this forum today about alleged ‘acts of terrorism’ from Ukraine. But the distinction between Ukraine striking military targets and Russia hitting civilian targets is a critical one, both morally and under international law.

There is a clear difference. Ukraine’s drone and missile strikes have been targeting military infrastructure within Russian territory or illegally occupied regions. These include airbases, logistics hubs, ammunition depots, command and control centres and radar and missile systems. These strikes are intended to degrade Russia’s ability to wage war, especially its long-range bombing capabilities. Under international humanitarian law, Ukraine is within its rights to target military assets of an aggressor state, especially in self-defence.

In contrast, Russia has repeatedly launched drone and missile attacks on civilian areas across Ukraine. These have included Residential buildings, Hospitals and Schools, Energy Infrastructure and Emergency Services. In Kharkiv, over 50 explosions were recorded, damaging residential buildings and killing civilians. In Kyiv, three firefighters were killed while responding to earlier strikes. Lviv, Lutsk, and Chernihiv also suffered civilian casualties and infrastructure damage. The Office of the United Nations High Commissioner for Human Rights verified a total of 45,000 civilian casualties as of 30th April 2025 and specified that the real numbers could be higher.

Russian strikes on civilians or civilian infrastructure are either an attempt to terrorise the civilian population and break morale (rather than achieve legitimate military objectives), or a failure to adequately distinguish military targets and act proportionately for military necessity. These are not the actions of a nation seeking peace, despite what President Putin says. These are the acts of blatant retaliation from the Kremlin, following Ukraine’s most successful and comprehensive strike against Russian Strategic bomber air bases.

Russia’s continued occupation in Ukraine and escalating aggression are not only unlawful, but they are also unsustainable. President Putin’s full-scale invasion of Ukraine, has now dragged on for over 1,200 days, resulting in catastrophic losses - including an estimated one million Russian casualties. President Putin continues to sacrifice Russian lives and futures and must choose another path – one of peace, responsibility and respect for international law. We have seen what the brave men and women of Ukraine’s Armed Forces are capable of, and the UK will continue to provide them with the tools they need to defend their sovereignty and protect their people. We call on Russia to accept the unconditional ceasefire, return to the negotiating table in good faith, and end this illegal war. Thank you, Madame Chair.
