Chibok girls kidnapped by Boko Haram seen in 'proof of life' video

A video appearing to show the Nigerian schoolgirls kidnapped by Islamist group Boko Haram has emerged - two years after they were taken captive.

The footage shows 15 girls in black robes identifying themselves as the pupils abducted from school.

The girls were filmed saying they were being treated well but wanted to go home and be with their families.

It is reported to have been made in December and sent to the Nigerian government as "proof of life" during negotiations.

It is the first time the girls have been seen since a video in May 2014.

The mass abduction of 279 schoolgirls on April 14th 2014 sparked a global outcry and led to the #BringBackOurGirls campaign, which was backed by US First Lady Michelle Obama.

Dozens of the girls managed to escape but 219 remain missing.

The Nigerian authorities' failure to find and rescue them has attracted worldwide condemnation.

CNN showed the video to mothers of the girls, with some recognising their daughters.

"My Saratu," one tearful woman can be heard saying.

Two mothers also claimed to Reuters that they had identified their daughters in the video, while another said she recognised five of the missing girls.

"They were definitely our daughters...all we want is for the government to bring back our girls."
