Nigerian terrorist organisation Boko Haram has released a video which it claims shows the missing Chibok schoolgirls it kidnapped in April 2014. 

In the unverified video, several glum-looking women can be seen standing in the background while a masked, armed militant wearing combat gear speaks in Hausa. In the video, the man claims that five girls were recently killed in a government airstrike.

At one point, the militant summons one of the women and asks her a series of questions using a microphone. 

After giving her name and confirming she is from Chibok, the girl urges parents to “talk to the government so that we can be allowed to go home.”

The video was sent to Ahmad Salkida, a Nigerian journalist who fled to Dubai some years ago.

Salkida has previously said that he has a direct connection with the leader of Boko Haram, Abubakar Shekau.

The video ends with graphic footage of what appears to be the scene of a massacre, with bodies of men, women and children strewn across the ground. 

The April 2014 kidnapping of 276 schoolgirls horrified the world and led to a global campaign urging world leaders to do all they could to #bringbackourgirls. 57 of the kidnapped girls managed to escape over the following months.

Boko Haram wants to institute an Islamic caliphate in Nigeria and is opposed to women being educated. The group has repeatedly targeted its attacks on schools and children.

In claiming responsibility for the Chibok kidnappings, group leader Shekau said "Allah instructed me to sell them ... I will carry out his instructions."
