Here is a video from Boko Haram showing the girls from Govt Secondary School, Chibok, that were abducted on April 14th, 2014. From the video it looks like the girls are alive and well, and most importantly it looks like all of them have taken up Islam.
The video was released earlier today, and shows Shekau saying that he will release the schoolgirls when Boko Haram prisoners are set free. A classic Boko Haram move.
Here is a clip of the video.
