On "America's Newsroom," National Security Correspondent Jennifer Griffin reported on new video footage showing the daring rescue mission carried out last week by U.S. and Kurdish forces on an ISIS prison in Iraq.

Video shows Delta Force soldiers escorting hostages out of cells as gunshots ring out in the background. A black ISIS flag can be seen on one wall.

Griffin says the video was captured on a Kurdish soldier's helmet-cam and provided to the media by the Kurdish government.

U.S. Central Command then released video from a U.S. warplane destroying the prison from the air after the prisoners were out.

"The video from the inside the prison clearly shows that U.S. troops are on the ground and in combat," Griffin said.

Griffin said the video also attempts to answer "Was the operation worth it?" by showing 70 Iraqi hostages who were slated to be executed by ISIS the next day.

Master Sgt. Joshua L. Wheeler died helping Kurdish forces charge into the compound, becoming the first U.S. casualty in Iraq since U.S. forces pulled out in 2011.

His remains were returned to Dover Air Force Base over the weekend, in what Griffin describes as "a very tough loss for this Delta Force unit."
