New videos released by Boko Haram -- the Islamic terrorist group -- purportedly show about 100 of the girls kidnapped from a Nigeria school last month and group leaders calling for the release of imprisoned militants.
The girls can be seen praying in one video, which runs 17 minutes and was obtained by AFP. The girls are wearing hijabs and reciting the Koran.

"Praise be to Allah, the lord of the world," the girls chant in the video, according to AFP.
In another, the terror group's leader, Abubakar Shekau, said he's willing to exchange the school girls for imprisoned Boko Haram members.
The Nigerian government is aware of the group's request -- but prisoner exchanges are considered "very tricky" for the Nigerian government.
