Exclusive: Mother of escaped Chibok girl speaks to BBC

Two years ago, the Nigerian Islamist group Boko Haram abducted 276 school girls from the northern town of Chibok.

Some managed to escape within hours of their kidnapping, mostly by jumping off the lorries and running off into the bushes.

In total 219 girls were taken away. In May 2016, one girl was found after escaping from the Sambisa Forest and is now in the care of the government in the capital, Abuja.

Her mother, Binta Ali, spoke exclusively to the BBC about what her daughter's life was like under the militant group.
