Eighty-two Chibok schoolgirls seized three years ago by Boko Haram have been freed in exchange for detained suspects with the extremist group, Nigeria's government announced yesterday, in the largest release negotiated yet in the battle to save nearly 300 girls whose mass abduction exposed the mounting threat posed by the Islamic State-linked fighters.

The released schoolgirls met with President Muhammadu Buhari on Sunday evening. Photos released by the government showed the president standing and addressing the Chibok schoolgirls at his official residence Sunday evening, a day after their release.
