A disturbing new video released by ISIS shows the dramatic militant ambush in Niger last October that left four US special forces soldiers dead.

Staff Sgt. Bryan Black, Staff Sgt. Jeremiah Johnson, Sgt. La David Johnson and Staff Sgt. Dustin Wright were killed as they returned from a low-risk patrol in Tongo Tongo with 30 Nigerian and up to 11 American soldiers, CBS News reported.

The more than nine-minute video was taken with a helmet camera worn by Johnson, according to the Daily Mail, which viewed the video. It was released by ISIS Sunday.

The graphic footage begins with the Green Berets trying to take cover behind an SUV as ISIS militants surround them. The soldiers fire colored smoke grenades in hopes of alerting friendly aircraft overhead before running for cover – but it’d be another two hours before French aircraft would arrive.

One of the soldiers is struck by a bullet and dragged by another behind the SUV.

At one point, Johnson goes down screaming as armed ISIS fighters come into view. One last shot apparently fired at point-blank range then fills the screen. The camera cuts off.

The video also shows still photos of the bodies of the slain American soldiers and evidence that their bodies were mutilated, the Mail reported.

The Pentagon is expected to release findings from its investigation into the Niger attack later this week, CBS said. It has not yet commented on the new video.

President Trump sparked outrage after telling Johnson’s widow that the Green Beret “knew what he signed up for … but when it happens, it hurts anyway.”
