and Abdullahi Ali Omar became Somali chief of army on 10 February 2007. On 20 January 2007, through United Nations Security Council Resolution 1744, the African Union Mission in Somalia (AMISOM) was formally authorised. Seven hundred Ugandan troops, earmarked for AMISOM, were landed at Mogadishu airport on 7–8 March 2007. In Mogadishu, Hawiye residents resented the Islamic Courts Union's defeat. They distrusted the TFG, which was at the time dominated by the Darod clan, believing that it was dedicated to the advancement of Darod interests in lieu of the Hawiye. Additionally, they feared reprisals for massacres committed in 1991 in Mogadishu by Hawiye militants against Darod civilians, and were dismayed by Ethiopian involvement. Critics of the TFG likewise charged that its federalist platform was part of a plot by the Ethiopian government to keep Somalia weak and divided. During its first few months in the capital, the TFG was initially restricted to key strategic points, with the large northwestern and western suburbs controlled by Hawiye rebels. In March 2007, President Ahmed announced plans to forcibly disarm militias in the city. According to the ISA, a coalition of local insurgents led by Al-Shabaab subsequently launched a wave of attacks against the TFG and Ethiopian troops. The allied forces in return mounted a heavy-handed response. All of the warring parties were responsible for widespread violations of the laws of war, as civilians were caught in the ensuing crossfire. Insurgents reportedly deployed militants and established strongholds in heavily populated neighborhoods, launched mortar rounds from residential areas, and targeted public and private individuals for assassination and violence. TFG forces alleged to have failed to efficaciously warn civilians in combat zones, impeded relief efforts, plundered property, in some instances engaged in murder and violence, and mistreated detainees during mass arrests. According to HRW, the implicated TFG forces included military, police and intelligence personnel, as well as the private guards of senior TFG officials. Victims were often unable to identify TFG personnel, and confused militiamen aligned with TFG officials with TFG police officers and other state security personnel. In May 2007, U.S. diplomats spoke with the TFG's Ambassador to Ethiopia. Among the topics of conversation were Somali security forces, and Ambassador Abdulkarim Farah said that the TFG had trained nearly 7,000 militia in Baledogle who were now patrolling throughout Somalia, from Kismayo to Puntland. Another 3,500 militia were undergoing training. Farah said that on 18 May
