Twenty-one of the over 200 schoolgirls abducted by Boko Haram in 2014 have been freed by the sect, Sahara Reporters and the British Broadcasting Corperation have reported.
Both organisations said a government official, who declined to be named, informed them.
In its exclusive report, SR said the government official informed it that the girls were picked up by a military helicopter after their release.
A top military source who spoke to our correspondent on the condition of anonymity said a major activity was taking place at Banki, a border town between Nigeria and Cameroon.
“I can confirm to you that there is a major activity going on in the Banki axis. For now, that is what I can tell you,” the source said.
The Nigerian Army and the Federal Government have yet to confirm the reports.
