In a bizarre new video reportedly released by ISIS late Tuesday that resembles a Hollywood movie trailer, the Sunni militant group appears to threaten to kill American troops in Iraq. The short clip, apparently a preview of a longer video called "Flames of War," ends with the message, "fighting has just begun" and that more is "coming soon."

The video was released hours after Gen. Martin E. Dempsey, the chairman of the Joint Chiefs of Staff, testified before the Senate Armed Services Committee that ground troops might be necessary in the military campaign against ISIS in Iraq. In the clip, audio of Obama saying, "American combat troops will not be returning to fight in Iraq," can be heard. The video also comes after a televised address from Obama last week, where he vowed to "degrade and ultimately destroy" ISIS.

The House is set to vote today to allow the U.S. to train and arm Syrian rebels in the country, where ISIS has taken sanctuary. "If we want to open a front against (Islamic State forces) in Syria, we have to open a front. And I don't see any other way to do it than try to build an alternative force," Rep. Adam Smith of Washington, lead Democrat on the House Armed Services Committee, told the Associated Press. "No one's excited about it but, you know, it's the best from a series of bad options."
