ACCRA, Ghana—Nigeria's Islamist insurgency on Monday kidnapped some 20 girls just miles from a small town where the group abducted several hundred schoolgirls in April, local officials said, in an attack that exposed the military's absence in an area the president pledged to protect.
The village of Garkin Fulani was preparing for its weekly market early Monday when Boko Haram fighters pulled up in a tractor trailer and began pulling young girls into the truck, said Adu Ibrahim, the area's chairman for a vigilante group called the Civilian Joint Task Force.

Nigerian authorities failed to act on warnings about Boko Haram raid on school

Amnesty International has confirmed through various sources that Nigeria’s military headquarters in Maiduguri was aware of the impending attack soon after 7:00 PM on 14 April, close to four hours before Boko Haram began their assault on the town.
