A video released by Islamist militants Boko Haram in May claimed to show around 100 girls kidnapped from a Nigerian school. The group’s leader, Abubakar Shekau, said the girls would be held until all imprisoned Islamic militants had been freed.
Boko Haram said the girls have converted to Islam.
The girls recited the first chapter of the Koran in the video.
About sixty abducted girls escaped Boko Haram Islamists in northeast Nigeria this week.
The South China Morning Press reported:
More than 60 women and girls abducted last month by suspected Boko Haram militants in northeast Nigeria have escaped their captors, sources said on Sunday.
Local vigilante Abbas Gava said he had “received an alert from my colleagues … that about 63 of the abducted women and girls had made it back home” late on Friday.
A high-level security source in the Borno state capital Maiduguri, who requested anonymity because he was not authorised to speak on the matter, confirmed the escape.
Gava, a senior official of the local vigilantes in Borno state who are working closely with security officials, told journalists the women escaped when their captors went out to fight.
“They took the bold step when their abductors moved out to carry out an operation,” he said.
Clashes took place between the Islamists and the army late on Friday after an attack by the insurgents in the town of Damboa, where more than 50 of them were killed, the army had said.
Spokesmen for the armed forces or the government could not be reached on Sunday for comment.
