The leader of Nigeria's Islamic extremist group denies agreeing to a cease-fire and says more than 200 kidnapped schoolgirls all have converted to Islam and been married off.
Abubakar Shekau dashed hopes for a prisoner exchange to get the girls released and says "in this war, there is no going back." He spoke in a video released late Friday night and received by The Associated Press in the same way as previous messages.
