Girl who escaped Boko Haram captors says she'll "never go back" to school

OutFront tonight – will Nigeria negotiate with terrorists? And will the U.S. help?

The Nigerian government could end up negotiating with Boko Haram after the leader of the terrorist group that kidnapped more than 200 schoolgirls last month appeared in a video saying they'll keep the girls until certain prisoners are released by Nigeria.

Another part of that same video, released today by French news agency Agence France-Presse, shows a large group of girls reciting a passage from the Koran with their heads covered.

If it's confirmed these are the girls who were taken almost a month ago, this would be the first glimpse the world has gotten of them since their abduction.

U.S. officials are now closely examining this video for clues, and they say they have no reason to believe the tape is not authentic – although it is unclear when the tape was made.

While the fate of the girls on that tape is still unknown, there were 53 girls taken that day who managed to escape. CNN's Nima Elbagir made the daunting trip to their village, speaking with one of the girls who escaped and the mothers of two of the girls who are still missing.
