Nigerian Islamist group Boko Haram has released a video supposedly showing some of the abducted Chibok school girls.
About 50 girls are seen in the video behind a militant demanding the release of fighters in return for the release of the girls.
A Nigerian blogger, Ahmad Salkida, who broke news of the release of the new video, said it was issued by the faction headed by Abubakar Shekau.
In the video a masked man stands behind dozens of girls, one of them identified as Maina Yakubu, who tells him she is from Chibok. She is veiled.
“What I want to tell my parents and the federal government is that the federal government should please release Boko Haram members in custody of security agents so they too can be released”, she said.
“Military jets have killed some of the girls”, she added.
The militant also said some girls had been killed by air strikes. The was no immediate comment from the Nigerian army.
276 schoolgirls from the Government Girls’ Secondary School in Chibok were kidnapped by Boko Haram about some 2 years ago.
The militant group still has about 219 of the girls.
It is the third time a video has been released showing the girls since the were kidnapped.
Abubakar Shekau, who has previously been declared dead by the Nigerian military, resurfaced two weeks ago after the so-called Islamic State declared Abu Musab al-Barnawi as the new leader of the group.
