BEIRUT (AP) — The militant Islamic State group released a video warning the United States that its fighters are waiting for it in Iraq if President Barack Obama sends troops there, as his top general said may happen if the current strategy of airstrikes fails.

The slick 52-second video entitled “Flames of War” shows militants blowing up tanks and images of wounded U.S. soldiers. It then shows a clip of Obama saying that combat troops will not be returning to Iraq, ending with a text overlay that reads “fighting has just begun.”
