Chadian soldiers prepare to leave an African-led International Support Mission to the Central African Republic (MISCA) military camp in Bangui on April 4, 2014. The UN accused Chadian soldiers on April 4 of carrying out an unprovoked attack when they opened fire in a crowded market in the Central African Republic's capital Bangui, killing at least 30 people. The damning findings came a day after Chad -- under fire over the Saturday attack, which also left 300 people wounded -- angrily announced it was withdrawing from the African peacekeeping force struggling to restore security in the strife-torn state.
