Newspapers with various front page headlines on the Chibok girls and their possible release are displayed at a news stand in Abuja October 18, 2014. Nigeria said on Friday it had agreed a ceasefire with Islamist militants Boko Haram and reached a deal for the release of more than 200 schoolgirls kidnapped by the group six months ago. There was no immediate confirmation from the rebels, who have wreaked five years of havoc in Africa's top oil producer and triggered an international outcry by seizing the girls from the northeast town of Chibok in April.
