Nigeria troops arrest 400 Boko Haram fighters and families

Military authorities say Nigerian soldiers have arrested more than 400 people associated with the Boko Haram extremist group hiding on the islands of Lake Chad, including fighters, wives and children.

The two-week operation netted the largest number of arrests of Boko Haram fighters in recent months in north-east Nigeria, said Colonel Onyema Nwachukwu. The operation included air and ground offensives.
