The Boko Haram militants reportedly handed over 21 missing Chibok schoolgirls to the Nigerian Government on Thursday morning.
According to a source, the girls, who have not been named, remain in Maiduguri, reports the CNN.
The militants had kidnapped 276 girls from a school in Chibok in northern Nigeria in April 2014.
As many as 57 girls escaped and shared harrowing tales of fleeing from the nearby Sambisa Forest, believed to be the terrorist group's stronghold.
Dozens are still missing and their whereabouts remain a mystery. They are, however, believed to be somewhere in the forest.
The kidnapping sparked global outrage and prompted global figures such as activist Malala Yousafzai and first lady Michelle Obama to support the campaign, #BringBackOurGirls.
In previous videos from the militant group, its leader Abubakar Shekau demanded the release of Boko Haram fighters in exchange for the Chibok girls.
However, according to the source, no Boko Haram fighters were released in exchange for the girls and the release happened as a result of a series of high-level negotiations involving a group from Geneva, according to the source.
