Damask, Nigeria - Chadian soldiers leave the battlefield by helicopter after fighting Boko Haram militants on March 18. The militant group, which controlled this town near the southern border of Niger for months, was ousted by a joint operation involving troops from Chad and Niger. At least 70 bodies, with their throats slit or decapitated were found dumped on the outskirts of town, their identities unknown. Nigeria's President Goodluck Jonathan told the BBC he hoped to recover all the territory ruled by Boko Haram within a month. "They are getting weaker and weaker by the day," he said.
