Islamic State, on Tuesday, released a new propaganda video, purportedly in response to President Barack Obama’s decision to extend airstrikes on the Sunni extremist group's strongholds in Syria.

The new video, titled “Flames of War,” was released late Tuesday by the Al Hayat Media Center, which, according to the Washington-based Middle East Media Research Institute, was established in May as the media arm of the Islamic State.

The 52-second-long video, which, at first glance, seems more like a video-game trailer, is replete with slow-motion effects and high-definition images. It shows exploding tanks and Islamic State militants apparently preparing to execute captives before the words "Flames of War" flash on the screen, followed by the words, "Fighting has just begun.” And, before the screen fades to black, the video ends with the words, “Coming Soon.”

The video, similar to previous videos showing the killings of foreign captives, is marked by high production quality and slick editing.

The video was released just hours after General Martin Dempsey, chairman of the Joint Chiefs of Staff, said at a Senate hearing that American ground troops may be needed to battle Islamic State forces in the Middle East, The New York Times reported. Obama has so far ruled out sending in troops to combat Islamic State forces on the ground in Iraq and Syria.
