Chris Olukolade, Nigeria's top military spokesman, 2nd left, Mike Omeri, Director General, National Orientation Agency, 2nd right, and Frank Mba, National police spokesman, attend a press conference on the abducted school girls in Abuja, Nigeria, Monday, May 12, 2014. A Nigerian Islamic extremist leader says nearly 300 abducted schoolgirls will not be seen again until the government frees his detained fighters. A new video from Nigeria's homegrown Boko Haram terrorist network received Monday purports to show some of the girls and young women chanting Quranic verses in Arabic. The barefoot girls look frightened and sad and sit huddled together wearing gray Muslim veils. Some Christians among them say they have converted to Islam. (AP Photo/Sunday Alamba)
