The Somali Civil War (2009–present) is a phase of the Somali Civil War which is concentrated in southern and central Somalia. It began in late January 2009 with the conflict mainly between the forces of the Federal Government of Somalia assisted by African Union peacekeeping troops and al-Qaeda aligned al-Shabaab militants. The conflict began in January 2009 when Ethiopian troops withdrew from Somalia, providing al-Shabaab with a power vacuum in the country in which to expand. The Islamists achieved arguably their largest success to date with the capture of Baidoa, the interim capital of the Transitional Federal Government (TFG). Al-Shabaab continued the conflict against the TFG and AMISOM throughout 2010, enjoying greater success when fighting the government forces. Local support for the organisation continued to grow, helped in part by the relatively successful law enforcement and justice system introduced in areas governed by al-Shabaab. The Kenyan invasion of southern Somalia, Operation Linda Nchi, began in October 2011. The Kenyan government had become concerned by the growing refugee crisis and instability along its porous northern border, and intended to create a buffer-zone to prevent over-spill of the conflict into Kenyan territory. Al-Shabaab came under increasing pressure from the Kenyan intervention, which joined TFG and AMISOM troops in attacking the group. This combination challenged al-Shabaab's position in the south and drove the Islamists from the important port city of Kismayo. Somalia suffered a severe famine during 2011, further weakening al-Shabaab. Despite the growing challenges, al-Shabaab still controls large swarths of territory in southern Somalia. It remains influential in many rural areas, and it now prioritizes guerrilla and terror attacks over territorial acquisitions. The Islamic State in Somalia (ISS) and Hizbul Islam have also carried out attacks against both factions. In 2013 Hizbul Islam renounced violence against the government, but as of 2022, ISS remains active in northern Somalia. 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
