A federal government official says that five Boko Haram commanders have been released in exchange for the 82 Chibok girls.

The confirmation Sunday comes a day after the young women were liberated after more than three years in captivity by the Islamic militants.

There was no comment yet from the presidency or Boko Haram, an extremist group linked to the Islamic State. The official who confirmed the release spoke on condition of anonymity as he was not authorized to speak to reporters on the matter.

Authorities say 113 of the 276 girls abducted from their boarding school back in 2014 remain missing. Girls who escaped said some of their classmates had died from illness. Others did not want to come home either because they'd been radicalized by their captors.

Amnesty International says the 82 freed Chibok schoolgirls should be quickly released to their families and not be subjected to lengthy government detention.

The rights group's Nigeria office also says the girls don't deserve to be put through a "publicity stunt that largely doesn't reckon with their privacy."

The newly released schoolgirls were set to meet with President Muhammadu Buhari in the capital later Sunday.

Amnesty International is calling for more attention to victims of "less-publicized mass abductions" by Boko Haram extremists. The group had seized thousands of captives in less than a decade.
