Former Islamic Extremist on Terror Threat: ISIS 'Will Stop at Nothing'

Filmed in an unknown location in Afghanistan, a new video shows ISIS militants burying several explosive charges beneath the ground.

Ten prisoners are blindfolded and led to where the bombs have been buried before they are forced to their knees. The jihadis then detonate the charges, killing all the prisoners.

The man who shot Usama Bin Laden, Rob O'Neill, joined Greta Van Susteren "On The Record" tonight to react to the shocking video.

"All they're trying to do is one-up themselves with being the worst, vile human beings they can," O'Neill said. "They're trying to kill people in the worst possible way. And they're doing it to taunt us, because they're not afraid of us right now."

He said the U.S. needs to admit that the problem is radical Islamic terror and lead the charge against the terror group.

"We are so afraid of offending people. We're letting them literally cut children in half over there, and we do nothing about it. We can't even admit that they're bad guys."
