Activists say one of the missing Chibok girls has been found in Nigeria, the first to be rescued since they were taken by Boko Haram militants two years ago.

The 276 girls were abducted from their secondary school in north-east Nigeria by the Islamist fighters in April 2014.

Activists have confirmed to the BBC that the girl was found by a vigilante group in the Sambisa Forest, close to the border with Cameroon.

The girl, Amina Ali Nkek, was reportedly identified by a civilian fighter who recognised her.
