A new video issued by Nigerian militant group Boko Haram's leader Abubakar Shekau claims to show some of the nearly 300 missing schoolgirls, who Shekau claims have converted to Islam.

Speaking in a video obtained by French news agency Agence France Presse, the militants' leader said the girls will not be released until Boko Haram prisoners were freed.

He then showed what he said were about 130 of the girls, wearing full-length hijabs and praying in an undisclosed rural location.
