The Islamic State released a chilling propaganda video late Tuesday warning the U.S. that "fighting has just begun."
The 52-second video, which mimics a Hollywood movie trailer, was titled "Flames of War" and threatened American troops. It was pulled by YouTube Wednesday.
WATCH: Islamic State releases video warning to U.S. (content warning: disturbing, graphic footage):
The video contained what appeared to be CGI explosions and footage of U.S. soldiers being wounded by militants.
It concluded with President Barack Obama saying combat troops would "not be returning to fight in Iraq." That audio was played over a clip showing a militant holding a handgun with captives on their knees before him. It was followed by a title slide which read "coming soon."
The release of the blockbuster-style trailer came one day after General Martin Dempsey, the chairman of the Joint Chiefs of Staff, warned he would recommend sending in ground troops if airstrikes alone failed to stop the Islamic State.
