At least 31 Nigerian soldiers were killed when ISIS-aligned militants ambushed a military convoy escorting weapons and overran a base in northeast Nigeria's Borno state, military sources told AFP Monday.
Fighters from the ISIS West Africa Province (ISWAP), arriving in around 20 vehicles, attacked the convoy on Sunday in the town of Mainok outside the regional capital Maiduguri, killing troops and seizing weapons before storming a nearby base, the two sources said.
