In November 2013, the Foreign Ministries of Somalia and Kenya and the UNHCR signed a tripartite agreement in Mogadishu paving the way for the voluntary repatriation of Somalia nationals living in Dadaab. Both governments also agreed to form a repatriation commission to coordinate the return of the refugees. This repatriation effort was in response to an attack on the Westgate shopping mall in Nairobi, and belief that Al-Shabaab, the militant group responsible for the attack, was using Dadaab to recruit new members.
