In a purported new ISIS video from “Wilayat North Baghdad,” Iraq, The militants carry out mass killings of “apostates.” The new video was released on September 22 on ISIS terrorist channels. The snuff film was shot around Baghdad, the capital of Iraq. ISIS invaded the capital city during the Iraqi Civil War in 2014.

In the video, ISIS militants are shown rounding up and mass executing “sahwat.”

According to the Long War Journal, “the Islamic State’s opponents… are part of the “sahwat,” meaning they are supposedly part of the “awakenings,” which received crucial assistance from the US during the fight against the Islamic State’s predecessor organization, al-Qaeda in Iraq (AQI).”

Syria Direct further reports that the sahwat “stabbed ISIS in the back” and that has made them a target by the ISIS. It is unclear which side the sahwat are fighting with or for now and if they still have American assistance or not.

In the video, which contains multiple execution portions, alleged sahwat men are rounded up by militants.

In one disturbing portion of the video, at least two dozen men are shown on their knees in a pre-dug mass grave as ISIS militants walk around executing them.

Later, ISIS militants storm a home of alleged sahwat men and execute more there. Others are handcuffed and blindfolded and led outside for a similar line of mass executions.

The video strikes a dark resemblance to World War II and photographs of Nazi Germany war crimes.
