Chibok girl 'happy' over schoolmates' release

One of the kidnapped Chibok schoolgirls has been speaking to the BBC about the release of 21 of her classmates.

Rebecca Ishaku was among the 270 students abducted by Boko Haram militants in April 2014.

But she managed to escape in the hours following the mass kidnapping when she jumped off a truck.

The BBC's Martin Patience began by asking her reaction to her schoolmates' release.
