Hundreds of Nigerian troops missing after Boko Haram ambush, media says

ABUJA - Hundreds of Nigerian troops went missing following an ambush by suspected Boko Haram extremists in Nigeria's northeastern state of Borno, local media and residents said on Sunday.

The militants invaded a base holding more than 700 soldiers in Yobe state in an hourslong onslaught on Saturday night, a military source said on condition of anonymity.

Fewer than 100 soldiers have returned following the attack, which took place just 24 hours after Boko Haram extremists ambushed a military convoy in neighboring Borno state on Friday.
