(AP) – Nigeria’s government is negotiating the release of another 83 of the Chibok schoolgirls taken in a mass abduction two-and-a-half years ago, but more than 100 others appear unwilling to leave their Boko Haram Islamic extremist captors, a community leader said Tuesday. The unwilling girls may have been radicalized by Boko Haram or are ashamed to return home because they were forced to marry extremists and have babies, chairman Pogu Bitrus of the Chibok Development Association told The Associated Press in a telephone interview.
