The BBC is quoting a Nigerian woman who said she saw over 50 of the abducted Chibok girls in Gwoza, a stronghold of the dreaded Islamic group, Boko Haram.
She saw the girls in the north-eastern Gwoza town before the Boko Haram militants were driven out of there by regional forces.
The Nigerian woman, who lived under Boko Haram's rule in Gwoza, told the BBC she saw the girls in Islamic attire, being escorted by the militants.
"They said they were Chibok girls kept in a big house," said the woman, who asked not to be identified for fear of reprisals.
"We just happened to be on the same road with them," she told the BBC.
The girls were abducted from their school in Chibok, a town in Borno State a yea ago.
