The Nigerian government announced that 82 of the girls who had been taken from a school in Chibok, Nigeria, three years ago had been released in exchange for as many as six suspected Boko Haram militants.

The Nigerian government negotiated the release of dozens of the nearly 300 girls kidnapped three years ago. As many as six suspected fighters may have been returned in exchange.

The raid, carried out shortly after the killing of a Navy SEAL team member, was part of Somalia’s renewed effort to rout the Shabab, the Islamist militant group.
