KANO, Nigeria: Boko Haram yesterday released a new video purportedly showing some of the Nigerian schoolgirls kidnapped from Chibok more than two years ago, and called for its detained fighters to be freed. The government said it was in touch with those claiming to be behind the undated video, which shows groups of girls in Islamic dress standing or sitting around a masked man armed with an assault rifle.

The film was issued just days after embattled Boko Haram head Abubakar Shekau denied claims he had been replaced as the leader of the Nigeria-based jihadist group. The mass kidnapping of 276 schoolgirls from Chibok in April 2014 provoked global outrage and brought unprecedented attention to Boko Haram and its bloody quest to create a fundamentalist state in northeastern Nigeria. A man wearing camouflage gear in the video called on the government to release Boko Haram fighters in exchange for the girls.

"They should immediately release our brethren in their custody," the man said, warning that if the prisoners are not released the government will never be able to rescue the girls. "They should know that their children are still in our hands," he said in the film posted on YouTube that appears to show some women injured after an air strike. While President Muhammadu Buhari has said the group is "technically defeated", his government has struggled to find the girls, an enduring political embarrassment that highlights Boko Haram's continued presence in the region.

The video was attributed to the original Boko Haram name, not the new Islamic State West Africa Province (ISWAP), suggesting it was released by Shekau's faction, although it is not known when or where it was filmed. "There are a number of the girls, about 40 of them, that have been married," said the man in the 11-minute video. "Some of them have died as a result of aerial bombardment." A girl speaking in the Chibok dialect chokes back tears as she describes an air strike by Nigerian armed forces. In the background, several girls look visibly distressed and dab their eyes. One is holding a small baby.

"This focuses on using the girls as a bargaining chip," Ryan Cummings, director at intelligence firm Signal Risk, told AFP. "The video shows that the war effort is hurting the operations of the group," he said. "It does have a sense of almost desperation from Boko Haram." The Nigerian government said it is in contact with those claiming to be behind the video but was acting cautiously given the leadership split. "Since this is not the first time we have been contacted over the issue, we want to be doubly sure that those we are in touch with are who they claim to be," Information Minister Lai Mohammed said in a statement.

Last week, the shadowy Shekau appeared in a video vowing to fight on, shrugging off an apparent split after he was said to have been replaced by Islamic State-backed rival Abu Musab Al-Barnawi. Barnawi has criticized Shekau's indiscriminate and brutal leadership in Nigeria that has seen Boko Haram fighters kill thousands of people in mosques and markets and raze entire cities. In March 2015, Shekau pledged allegiance to the Islamic State and changed Boko Haram's name to ISWAP, prompting fears the Nigerian insurgency would be bolstered by its connection to the global jihadists.

However, there have been few signs that Boko Haram has benefited from the alliance, as the Nigerian military recaptures territory once controlled by the insurgents. Over the past year, the military has announced the rescue of hundreds of people, most of them women and children, who were kidnapped by Boko Haram. But the missing Chibok girls were not among them, despite several unconfirmed sightings.

In the hours that followed the 2014 mass kidnap, dozens of girls managed to escape. Of the 219 still missing, just one was found, Amina Ali, in May this year near the Sambisa Forest area of Borno state, a known Boko Haram hideout. Abubakar Abdullahi, a spokesman for the Bring Back Our Girls movement, told AFP that one of the girls had been identified in what he described as a "heartbreaking" video. "One of our members has recognized a girl. We are still in the process of confirming a few of the girls," Abdullahi said. "We've always believed they will be back, but it's also painful," he said, criticizing the government for being unable to rescue the girls. "The frustration will always be there. We failed them on so many instances."

Boko Haram has been blamed for some 20,000 deaths and displacing more than 2.6 million people since it launched a brutal insurgency in Nigeria in 2009 that has since spread into several neighboring countries. - AFP
