In this picture taken Monday Feb. 18, 2013, children gather at the door of Mohamed Salia's madrassa in Gao, northern Mali. Nearly a month after the al-Qaida-linked militants were driven out of Gao and into the surrounding villages, students are now returning to the city's Quranic schools. Many classrooms, though, are still half full, as tens of thousands of people fled the fighting and strict Islamic rule imposed by the extremists. (AP Photo/Jerome Delay)
