The leader of Nigeria's Islamist Boko Haram militants - Abubakar Shekau - has said he would release more than 200 schoolgirls abducted by his fighters in exchange for prisoners, according to a video seen by Agence France-Presse.
The French news agency said the 17-minute video showed about 100 girls wearing full veils praying in an undisclosed location.
The Nigerian military has flown more than 300 sorties in the hunt for the abducted schoolgirls, a Major has told ITV News' Rageh Omaar.
A newly released video from Boko Haram reportedly shows the kidnapped Nigerian schoolgirls.
The man who started a viral hashtag campaign in support of the kidnapped Nigerian schoolgirls says it has forced the government to act.
