The Islamic State has released a disturbing video showing them behead 10 Christians that the group claims to have captured in Nigeria. An 11th captive, shown in the video in the middle of the group, was shot in the head. 

ISIS didn’t release any details, but claimed that the men were all captured in the northeast state of Borno in Nigeria. They said these killings were to “avenge” the death of their leader Abu Bakr al-Baghdadi and his spokesman Abul Hassan al-Muhajir during a U.S. Delta Force raid in Syria in October.

The video showed the terror group in beige uniforms and black masks lining up behind blindfolded captives, then beheading 10 of them and shooting the 11th victim.

Nigerian President Muhammadu Buhari condemned the murders and pleaded with Nigerians not to let themselves become divided along religious lines.

“We should, under no circumstance, let the terrorists divide us by turning Christians against Muslims because these barbaric killers don’t represent Islam and millions of other law-abiding Muslims around the world,” he said in a statement.

A different video from ISIS said that the captives had been taken from Maiduguri and Damaturu in Borno, where the terrorists have been fighting to install an Islamist state. In that video, the captives pleaded for the President, Muhammadu Buhari and the Christian Association of Nigeria to come to their rescue.

The Islamic State West Africa Province  (ISWAP), broke away from Boko Haram and declared their loyalty to ISIS in 2016. They have used hostage-taking as a bargaining chip. This video, released over Christmas, may have been intended to turn Christians and Muslims in Nigeria against one another. 

In the video, a masked man said, “this is a message to Christians all over the world.”
