Between 31 May and 9 June 2008, representatives of Somalia's federal government and the moderate Alliance for the Re-liberation of Somalia (ARS) group of Islamist rebels participated in peace talks in Djibouti brokered by the UN. The conference ended with a signed agreement calling for the withdrawal of Ethiopian troops in exchange for the cessation of armed confrontation. Parliament was subsequently expanded to 550 seats to accommodate ARS members, which then elected a new president. With the help of a small team of African Union troops, the coalition government also began a counteroffensive in February 2009 to retake control of the southern half of the country. To solidify its control of southern Somalia, the TFG formed an alliance with the Islamic Courts Union, other members of the Alliance for the Re-liberation of Somalia, and Ahlu Sunna Waljama'a, a moderate Sufi militia.
