MAIDUGURI, Nigeria (AP) — More than 100 girls are still missing three days after suspected Boko Haram extremists attacked their school in northern Nigeria, parents said Thursday, as fears grew that they may have been kidnapped like those from Chibok town nearly four years ago. The announcement came after government officials in Yobe state acknowledged that some 50 young women remained unaccounted for in the Monday evening attack on the village of Dapchi. There have been a number of conflicting reports, in part because of limited access to the area.
