AMISOM – Background of Conflict

The UN—and the United States (U.S.) by extension—has an inconsistent history in Somalia. Somalia collapsed into anarchy after the overthrow of Mohammed Siad Barre’s regime in 1991. By 1992, the UN formed the United Nations Operation in Somalia (UNOSOM) [UNSCR 751(1992)] to provide humanitarian assistance. When the feuding clans compromised the delivery of the food, the U.S. authorized Operation Restore Hope, with U.S. forces dispatched to assist with the famine relief as part of the UN’s United Task Force (UNITAF). UNITAF transitioned to UNOSOM II in March of 1993. After the tragic events of 3 October 1993 (the deaths of 18 U.S. soldiers and hundreds of Somalis), the U.S. removed its troops. The UN withdrew all forces from Somalia by March 1995. 

For the next 15 years, Somalia endured frequent humanitarian crises, a short-lived Intergovernmental Authority on Development (IGAD) mission (IGADSOM), an invasion by Ethiopia, and the eventual ascendancy of the Islamist group al-Shabaab, which seized Mogadishu in 2006. 

AMISOM was created by the AU Peace and Security Council in January 2007 and approved by the UN Security Council a month later. In 2010, AMISOM assumed the offensive against Al-Shabaab. AMISOM is largely credited with driving Al-Shabaab out of Mogadishu and major population centers. In August 2017, UNSCR 2372 (2017) renewed the AMISOM mandate until 31 May 2018. This renewal included “the first-ever” reduction in forces for AMISOM while transitioning security responsibilities to Somali authorities.

In 2013, the UN established UNSOM  [UNSCR 2102(2013)], a Department of Political Affairs (DPA) field mission. In late March 2018, The UN Security Council renewed the UNSOM mandate with UNSCR 2408(2018) until 31 March 2019. The decision to extend “underscored the importance of the Mission’s support to the Somali Government‑led political process as well as the importance of its support to the federal Government of Somalia on preparations for the delivery of inclusive, credible and transparent elections” and “requested continued support for the Government’s efforts to implement the country’s National Strategy and Action Plan for Preventing and Countering Violent Extremism in order to strengthen Somalia’s capacity to prevent and counter terrorism.” UNSOM is responsible for the implementation of the UN Strategic Framework Somalia (2017-2020) as well as a specific policing mission.

Among other UN mandates with respect to Somalia are UNSCR 2383(2017) and UNSCR 2385(2017). In early November 2017, UNSCR 2383(2017) renewed authorization for international naval forces to combat piracy off Somali coast for another year. In summary, the UN Security Council:

…affirmed the primary responsibility of Somali authorities in the effort to combat piracy…(and)…renewed the call upon States and regional organizations that were able to do so to cooperate with those authorities and each other…(and)…commended the contributions of the European Union’s Naval Force (EUNAVFOR) Operation ATALANTA, the North Atlantic Treaty Organization’s (NATO) Operation Ocean Shield, the Combined Maritime Forces’ Combined Task Force 151, the African Union and the Southern Africa Development Community, as well as individual States for naval counter‑piracy missions and protecting ships transiting through the region…(and)…reaffirmed that the authorizations renewed in the resolution applied only with respect to the situation in Somalia and did not affect rights, obligations and responsibilities of Member States under international law, including the Convention on the Law of the Sea.

On 14 November 2018, UNSCR 2444(2018) extended the arms embargoes on Somalia and Eritrea until 15 November 2019, as well as providing: “authorization for maritime interdiction of illicit arms imports and charcoal exports, and the humanitarian exemption.”  It also decided to terminate the mandate of the Somalia and Eritrea Monitoring Group (SMEG) and replace it with a Panel of Experts to oversee sanctions.

Another UN mission operating in Somalia is the UN Support Office in Somalia (UNSOS). UNSOS was established by UNSCR 2245(2015). UNSOS is responsible for support to AMISOM, UNSOM, the Somali National Army (SNA) and the Somali Police Force (SPF) on joint operations with AMISOM. UNSOS’ most recent mandate renewal was UNSCR 2372(2017) (30 August 2017). Its period of existence is characterized as “open.”

Background by AMISOM

The African Union Mission in Somalia (AMISOM) is an active, regional peacekeeping mission operated by the African Union with the approval of the United Nations. It was created by the African Union’s Peace and Security Council on 19th January 2007 with an initial six-month mandate.

AMISOM replaced and subsumed the Inter-Governmental Authority on Development (IGAD) Peace Support Mission to Somalia or IGASOM, which was a proposed Inter-Governmental Authority on Development protection and training mission in Somalia approved by the African Union in September 2006.IGASOM was also approved by the United Nations Security Council.

Originally IGASOM was proposed for immediate implementation in March 2005 to provide peacekeeping forces for the latest phase of the Somali Civil War. At that time, the Islamic Courts Union (ICU) had not yet taken control of Mogadishu, and most hopes for national unity lay with the Transitional Federal Government (TFG). By May 2006, the situation was radically different, as the ICU had engaged the Alliance for the Restoration of Peace and Counter Terrorism or ARPCT and was fighting for control of Mogadishu in the Second Battle of Mogadishu. By June, they had established control of the capital.

Plans for IGASOM continued, though by July there were indications of opposition from the ICU, who saw the initiative as a western means to curb the growth of Islamic movement. Until December 2006, the UN Security Council had imposed an arms embargo on the group, but the embargo was partially lifted and a mandate for IGASOM issued in December 2006.

On 20th February 2007, the United Nations Security Council authorised the African Union to deploy a peacekeeping mission with a mandate of six months, adopting resolution 1744(2007)13. The aim of the peacekeeping mission was to support a national reconciliation congress and requested a report within 60 days on a possible United Nations Peacekeeping Mission.

In October, 2014, the Security Council (Resolution 2182 (2014) gave a green light to the African Union to continue its mission in Somalia until 30th November 2015. Furthermore the council authorized the African Union mission to take all measures, as appropriate, to carry out support for dialogue and reconciliation by assisting with free movement, safe passage and protection of all those involved in a national reconciliation congress involving all stakeholders, including political leaders, clan leaders, religious leaders and representatives of civil society.

In August 2017, the UN Security Council issued resolution 2372 enabling the gradual handing over of security responsibilities from AMISOM to the Somali security forces contingent on abilities of the Somali security forces and political and security progress in Somalia.
