War in Somalia ( 2009 – present ) The 2009 – present phase of the Somali Civil War is concentrated in southern Somalia . It began in early February 2009 , with the conflict between the forces of the Federal Government of Somalia assisted by African Union peacekeeping troops and various militant Islamist groups and factions . The violence has displaced thousands of people in the southern part of the country . The conflict has also seen sectarian violence between the moderate Sufis ASWJ , and the Islamists Al - Shabaab . In 2011 , a coordinated military operation between the Somali military and multinational forces began . The mission was officially led by the Somali army , with analysts expecting the additional AU troop reinforcements to help the Somali authorities gradually expand their territorial control . Background . Established in 2004 and internationally recognized , the Transitional Federal Government ' s ( TFG ) support in Somalia was waning until the United States - backed 2006 intervention by the Ethiopian military , which helped drive out the rival Islamic Courts Union ( ICU ) in Mogadishu and solidify the TFG ' s rule . Following this defeat , the ICU splintered into several different factions . Some of the more radical elements , including Al - Shabaab , regrouped to continue their insurgency against the TFG and oppose the Ethiopian military ' s presence in Somalia . Throughout 2007 and 2008 , Al - Shabaab scored military victories , seizing control of key towns and ports in both central and southern Somalia . At the end of 2008 , the group had captured Baidoa but not Mogadishu . By January 2009 , Al - Shabaab and other militias had managed to force the Ethiopian troops to withdraw from the country , leaving behind an underequipped African Union ( AU ) peacekeeping force . A power sharing deal ensued between an Islamist splinter group led by Sheikh Sharif Sheikh Ahmed ' s Alliance for the Re - liberation of Somalia Djibouti faction ( ARS - D ) and TFG Prime Minister Nur Hassan in Djibouti . Al - Shabaab , which had separated from the moderate Islamists of the insurgency , rejected the peace deal and continued to take territories . It was joined by Hizbul Islam , which is an amalgamation of four Islamist group including the Alliance for the Re - liberation of Somalia – Asmara faction . Another Islamist group , Ahlu Sunnah Waljama ' ah , which was allied with the TFG and supported by Ethiopia , continues to attack al - Shabaab and take over towns as well although they have been effective only in the central region of Galguduud , where they ousted al - Shabaab from most of the region . After the parliament took in 275 officials from the moderate Islamist opposition , ARS leader Sheikh Ahmed was elected TFG President on 31 January 2009 . Since then , the al - Shabaab radical Islamists have accused the new TFG President of accepting the secular transitional government and have continued the civil war since he arrived in Mogadishu at the presidential palace in early February 2009 . Timeline . Islamist - ARS / TFG coalition conflict . On 4 February 2009 , four Islamist groups , including Hassan Dahir Aweys ' Eritrean branch of the ARS merged and created the group Hisbi Islam , to fight the new government of Sharif Ahmed . al - Shabaab also vowed to fight the government . On 8 February 2009 , they declared war on the new government of Sharif Ahmed and the AU peace - keepers . New TFG President Sheik Sharif Sheik Ahmed arrived in Mogadishu as a president for the first time on 7 February 2009 . The al - Shabaab and other radical Islamists began firing at the new TFG president hours later . They accused the new President of accepting the secular transitional government . On 8 February , heavy fighting broke out in southern Mogadishu . al - Shabaab leader Sheikh Mukhtar Robow ( Abu Mansur ) . met with Sharif Ahmed for peace talks during his visit to Mogadishu , while Omar Iman rejected the president . During these negotiations , Sharif Ahmed said that he would be prepared to enforce Sharia Law in Somalia , which is currently the radical groups ' main demand . However , Sheikh Mukhtar Robow , a former Al - Shabab spokesman , denied having talked to Sharif Ahmed and vowed to continue fighting until his demands for Sharia Law were met . Sheikh Mukhtar Robow warned Nigeria against sending peace keepers to Somalia , as al - Shabaab views the AU peace keepers as occupying forces and will continue fighting them until they withdraw from the country . On 10 February , al - Shabaab launched an offensive to take the Bakool province . Government officials who had been ousted from Baidoa had been amassing troops in the city of Hudur ( Xudur ) and planning a major offensive to re - take Baidoa . Islamist forces attacked the province and reached the capital were they started a battle against government forces . In Galmudug , Clan militia took the town of Masagaway from al - Shabaab . There was also fighting in Warsheekh . On 12 February , the spokesman for al - Shabaab , Sheikh Mukhtar Robow ( Abu Mansur ) , rebuffed reports from several media outlets that a mutual agreement between him and newly elected president Sharif Ahmed was made . He also added that he had no intention to contact the president on any matters , and that they would continue fighting against foreign troops and what he described as an “ apostate " government . The same day , they vowed war against the new government . On 22 February , a double suicide bomb attack on an AU base in Mogadishu left 11 Burundian soldiers dead and another 15 wounded . Two days later heavy fighting erupted in the city as TFG and AU forces attempted to retake the city from radical Islamist forces . The fighting lasted for two days and killed 87 people , including : 48 civilians , 15 insurgents and 6 TFG policemen . At the same time as the fighting raged in Mogadishu , al - Shabaab forces took the town of Hudor , to the north - west , in fighting that killed another 20 people : 10 TFG soldiers , 6 insurgents and 4 civilians . On 28 February , it appeared that Hisbi Islam would sign a ceasefire with the Transitional Federal Government . However , by 1 March , it was clear that no ceasefire would be given , despite President Sharif Ahmed having agreed to proposals for a truce and having offered to accept the implementation of Sharia Law but refused to move troops from civilian areas despite the Islamists doing so . On 6 May , al - Shabaab announced that it would continue the war even if AMISOM withdrew . 25 May , the government announced an immediate blockade on airstrips and seaports under insurgent control to stop the flow of weapons reaching them . On 7 May , a fierce battle for control of Mogadishu started between al - Shabaab and Hizbul Islam against the TFG . Hundreds were killed and injured and tens of thousands were displaced . By 11 May , rebel forces gained the upper hand and made large gains taking over most of the capital . Fighting continued until 14 May and , though they came close , the rebels didn ' t manage to overthrow the government . There were new rounds of fighting all through August . 16 May , al - Shabaab captured the strategic town of Jowhar , which connects Mogadishu with central Somalia . 5 June , Hizbul Islam captured Wabho in one of the largest battles of the war , which left 123 combatants killed . It was also rumoured Sheikh Hassan Dahir Aweys was injured in this battle . On 19 June , the transitional parliament speaker Sheikh Adan Mohamed Nuur Madobe asked the international community to send foreign troops to Somalia within the following 24 hours . He stated that the government ' s power is on the verge of being defeated by Islamist forces in the Somali capital . The Cabinet declared a state of emergency and Somalia asked for help from neighbors Kenya , Djibouti , Ethiopia and Yemen . Ethiopia refused saying intervention needs an international mandate . On 21 June , a spokesman for the al - Shabaab Islamists said they would fight any foreign troops . al - Qaeda also made threats against Kenyan intervention . 22 June , Somali President Sheikh Sharif Ahmed declared state of emergency in the country as a new round of fighting in Mogadishu left 12 dead and 20 injured . Hundreds were said to be fleeing the city 4 July , Sheik Abdinasir Jalil , a former commander of the training for ICU administration in Beledweyn town joined Hizbul Islam with his men and vowed to fight TFG forces in the city and attack Ethiopian forces in El - gal village , which lies 18 km from Beledweyn . He said that the government officials want to bring Ethiopian troops inside town and that is the reason they switched sides . Former ICU officials who joined Hizbul Islam , held a press conference and announced that the ICU administration in Hiraan had collapsed as they joined the insurgents . Sheikh Ibrahim Yusuf , a top security commander in Beledweyn , also defected along with his forces . General Muktar Hussein Afrah was sent to Beledweyn along with TFG troops and put in charge there by the TFG as the ICU administration had collapsed . Many ICU officials including MPs resigned that day next to Sheikh Abdinasir Jalil Ahmed ( head of training ) and Sheikh Ibrahim Yusuf ( head of security ) ; Sheik Osman Abdulle Barqadle , the army commander of Ugas Khalif airport , and Sheik Abdullahi Garamgaram , the deputy chief of the emergency forces also resigned . In response , TFG forces led by general Muktar Hussein Afrah started military manoeuvers in the East side of the city . 6 July , Sheikh Moktar Ali Zubeyr , the Amir of al - Shabaab gave government forces an ultimatum of 5 days to hand over their weapons . The ultimatum was rejected by Indho Ade . 17 July , two French security advisors to the government were captured by insurgents . The Somali government gave permission for French commandos to launch operations inside Somalia to free the 2 French nationals that held by al - Shabaab . On 22 July , French warships and helicopters were seen near the ports of Mogadishu and Marka as France declared they would undertake military operations to free the two French military advisers who had been captured by insurgents . One hostage , Marc Aubriere , escaped a month later in August 2009 . The second , Denis Allex , was seen in a video released in June 2010 asking for assistance to effect his release . On 15 September , a helicopter raid conducted by the US military killed 6 , including a key Al - Qaida member , Saleh Ali Saleh Nabhan . Al - Shabaab - Hizbul Islam conflict . The armed conflict between Hizbul Islam and al - Shabaab began due to a dispute between the faction of the Ras Kamboni Brigades led by Sheikh Ahmed " Madoobe " and al - Shabaab , over a power sharing agreement in Kisimayo . Hizbul Islam and al - Shabaab had made a power sharing agreement for the city , where the power would rotate between the two factions , with each faction controlling the city for periods of six months . However , due to clan politics al - Shabaab refused to let the power rotation take place . This led to internal problems within Hizbul Islam as its ARS - A and JABISO factions , which were aligned with al - Shabaab in Hiran and Mogadishu , refused to support the Ras Kamboni Brigades , while Anole remained neutral . It also led to a split within the Ras Kamboni Brigades , with a faction led by Hizbul Islam ' s deputy chairman Sheikh Hassan " Turki " refusing to back Ahmad " Madoobe " and instead siding with al - Shabaab . On 1 October , heavy fighting broke out . By the afternoon , al - Shabaab controlled most of the city with 12 dead and 70 wounded . At least 17 people were killed in during a series of battles overnight on 5 October . A Hizbul Islam spokesman claimed that they had captured foreign fighters in the battle . The battle was decisively won by al - Shabaab which expelled Madbobe ' s Ras Kamboni Brigade forces from the city . Throughout November 2009 , fighting between the two factions continued in Southern Somalia and as result insurgent attacks in Mogadishu targeting TFG and AMISOM forces decreased . However Sheikh Ahmad Madobe ' s forces were soon overpowered by al - Shabaab and its local allies and forced to withdraw from the Lower Jubba region and most of Southern Somalia . In February 2010 , Sheikh Hassan Turki ' s branch of the Ras Kamboni Brigades declared a merge with al - Shabaab . He encouraged other groups in Hizbul Islam also to join al - Shabaab . In early 2010 the two groups clashed in Hiran region , in central Somalia . This battle was also won by al - Shabaab which took control of the region . In late 2010 they also expelled Hizbul Islam from Bay region after seizing control of Bur Hakab , after a two days battle in which 30 militants were killed . In Lower Shabelle region al - Shabaab seized control of Hizbul Islam strongholds : Furuqley , Farsooley and Dugulle villages and then started preparing an offensive in Afgooye , the last town Hizbul Islam controlled in the region . Soon after Hizbul Islam was forced to surrender the Luuq District in Gedo region to al - Shabaab , after which it was announced that Hizbul Islam would merge with al - Shabaab . From mid - December al - Shabaab fighters started taking over Hizbul Islam positions . Hizbul Islam fighters also started entering al - Shabaab controlled areas of Mogadishu . The merge was confirmed on 20 December , when Hizbul Islam Chairman Sheikh Hassan Dahir Aweys and Sheikh Mohammad Osman Arus , the organisation ' s official spokesman , surrendered to al - Shabaab and disbanded the organisation . Galmudug and Islamists . Government officials from the Galmudug administration in the north - central Hobyo district also reportedly attempted to use pirate gangs as a bulwark against Islamist insurgents from southern Somalia ' s conflict zones . Other pirates are alleged to have reached agreements of their own with the Islamist groups , although a senior commander from the Hizbul Islam militia vowed to eradicate piracy by imposing sharia law when his group briefly took control of Harardhere in May 2010 and drove out the local pirates . Battle of Gashandiga . An early 2011 offensive was dubbed by AU Representative Wafula Wamunyinyi as the " Battle of Gashandiga . " In 20 February 2011 , it was reported that AMISOM troops destroyed a large complex of al - Shabaab trenches , and killed six al - Shabaab commanders in Mogadishu . Two AMISOM troops died in those battles . On 21 February , at least 20 people , including TFG policemen were killed in a suicide car bomb attack in Mogadishu . Between 21 and 22 February , twelve people were killed in heavy shelling in Mogadishu . On 25 February , 15 people were killed as al - Shabaab fighters attempted to re - take lost territory in Mogadishu . Additionally , rebels displayed one wounded and five dead Burundian AMISOM soldiers . On 26 February , an offensive by TFG troops with support of Ethiopian soldiers was opened in the southern Somali town of Bula Hawo . Until 28 February , 33 people were killed in TFG and Ethiopian shelling . By 5 March , AMISOM and TFG forces claimed to control seven of the city ' s districts , while six were contested and three were controlled by anti - government forces . Al - Shabaab responded to the government offensive by putting up roadblocks to prevent the movement of goods from the seaport . This adversely affected both sides of the conflict , as the TFG controlled the port and its profits , while the Bakaara Market , where many of the goods were bound to be sold , was controlled by the insurgents . It was reported that by 5 March , up to 53 AMISOM may have died in the clashes . Of those , 43 Burundian and 10 Ugandan . By 16 March , AMISOM was bolstered by an additional 1 , 000 peacekeepers to assist in the TFG ' s renewed offensive against al - Shabaab , bringing the total manpower of AMISOM to nearly 9 , 000 .

Witnesses reported Al - Shabaab vehicles abandoning their bases in the capital for the south - central city of Baidoa . The group ' s spokesman Sheikh Ali Mohamud Rage described the exodus as a tactical retreat , and vowed to continue the insurgency against the national government . Observers have suggested that the pullout may at least in part have been caused by internal ideological rifts in the rebel organization . After their withdrawal , al - Shabaab has however continued hit and run tactics in the North of the city as they vowed to continue guerilla attacks in Mogadishu . On 4 October 2011 , a suicide bomb on a lorry detonated and killed more than 70 people near a compound housing several government ministries . Two weeks later a car bomb killed at least two people . On 11 October 2011 , AU troops claimed to have driven the remnants of al - Shabaab out of the city . As of November 2012 , Mogadishu was still firmly in AMISOM and TFG hands , although the city continued to suffer from suicide bomb attacks . Fighting in Puntland . On 2 to 3 September , fighting was reported in Puntland that resulted in the deaths of up to 60 people , including 8 Puntland soldiers and 40 Al - Shabaab militants , with Insurgents being repelled .

Conversely , Al - Shabaab claimed they killed around 70 government aligned troops and captured 10 technicals . The Burundian military lost 51 soldiers in October , causing anger among Burundians , who believe that their country is sacrificing too much . Many Burundians have urged other AU members to contribute troops to the Somalia mission . Nigeria , Djibouti , and Guinea have indicated sending troops , but all have yet to contribute . Kismayo offensive . On 4 September 2012 the Kenyan Navy shelled Kismayo . This was part of an AU offensive to capture the city from al - Shabab fighters .
