One of the fathers of kidnapped Chibok schoolgirls has reportedly said he has recognised his daughter in a video released by Boko Haram on Sunday.

A spokesman for the Bring Back Our Girls movement, set up to demand the return of 276 schoolgirls kidnapped in April 2014, said he was “certain” of the identities of 10 other girls seen in the footage.

“When I heard her voice, I realised she is my daughter,” Kanu Yakubu told reporters in Abuja.

He was referring to Maida Yakubu, whom he identifies as the girl seen in the video choking back her tears as she describes an air strike by the Nigerian armed forces.
