Boko Haram had demanded that the government free of some of its members in exchange for the girls’ release.
According to BBC News reporter, Stephanie Hegarty, the 21 girls might have been released in exchange for the freedom of 4 Boko Haram prisoners.
“21 Chibok girls may have been swapped for 4 Boko Haram detainees,” Hegarty said citing a military source.
News of the girls’ released broke on Thursday, October 13, and has been confirmed by presidential spokesman, Garba Shehu.
“It is confirmed that 21 of the missing Chibok Girls have been released and are in the custody of the Department of State Services, DSS,” Shehu said via Twitter.
Boko Haram had, in August, demanded that the government free of some of its members in exchange for the girls’ release.
The Nigerian government has repeatedly admitted to negotiating with the sect but said that it wanted to tread with caution to ensure it was dialoguing with genuine members of the group.
