Boko Haram frees 82 Nigerian schoolgirls in swap for terrorists

The Islamist Boko Haram group have released 82 schoolgirls from a group of 276 they abducted in Chibok north-eastern Nigeria three years ago, the Nigerian president's office says. They were traded for an unknown number of captured terrorists after negotiations. The girls were brought from a remote area to a Nigerian army base near the Cameroon border. More than 100 girls are still held captive by Boko Haram. Many of the Chibok girls were Christian, but were forced to convert to Islam and to "marry" their kidnappers..
