At least 24 people have reportedly been killed by Boko Haram fighters at a military base in Nigeria. The attack happened in the northeastern town of Buni Yadi, in Yobe State. It is close to where Boko Haram gunmen fired at a high school in February, killing at least 59 students. The armed group has been fighting to create an Islamic state in Nigeria's mainly Muslim north.
