Islamic extremist terrorists who kidnapped 11 Christians in northeast Nigeria on Christmas Day have executed five of them, according to a video released by the Islamic State’s AMAQ News agency.

The 49-second video, dated Dec. 29, shows five armed members of the Islamic State West Africa Province (ISWAP) lining up behind five men dressed in orange robes who are kneeling with their hands tied behind them. Ordered in the Hausa language to state their names, each of the kneeling men in turn is heard saying their name and adding, “I’m a Christian.”
