82 school girls, who were among 276 girls abducted by Boko Haram in from Chibok in northeast Nigeria in 2014, have been freed.

Although details surrounding their release are not clear, early media reports indicate that a prisoner swap deal secured their release.

The girls arrived in the capital Abuja on Sunday and were received by President Muhammadu Buhari.

According to The International Committee of the Red Cross, which facilitated the negotiations, one of the girls arrived with a baby, who appeared to be less than two years old.

The 82 schoolgirls are now in the custody of the Nigerian army and the government has published the names of the freed girls on twitter so that their families can know if their daughters are among them since even with the latest release about 195 of the girls were are still reported missing.

Boko Haram fighters stormed the Government Girls Secondary School in Chibok on the evening of April 14, 2014, and kidnapped 276 teenaged girls. Fifty-seven managed to escape in the hours that followed but the remaining 219 were held by the group.

The abduction of the girls sparked a global outrage and a campaign titled #BringBackOurGirls was started to mount pressure on the Nigerian government to act.
