The Sunni extremist group that is ravaging large swaths of northern Iraq has warned it will attack Americans “in any place” should U.S. airstrikes kill any of its members, Reuters reports.

American airstrikes began earlier this month in an attempt to help thousands of people—members of the Yazidi, an ethnic minority in the region—who were trapped on a mountain range by fighters of the Islamic State of Iraq and Greater Syria (ISIS). President Barack Obama formally told Congress on Sunday that he had sanctioned additional air raids, though he said they would be limited. The new strikes, requested by the Iraqi government, were intended to help Iraqi and Kurdish security forces who had been battling the militants for control of the strategic Mosul Dam. Aided by U.S. air support, these troops successfully recaptured it on Aug. 18.

U.S. Central Command said at least 14 airstrikes were conducted on Sunday, and had successfully damaged or destroyed ISIS vehicles and one of its checkpoints. The group’s latest missive might reflect its anger towards the U.S., whose aerial support has allowed the Iraqi and Kurdish forces to reclaim some of the territory that ISIS had seized in a lightning offensive in June.

Reuters adds that the purported ISIS video shows an image of an American, who was beheaded during the U.S.-led war in Iraq that ended in 2011. The 45-second film also shows people being shot by snipers and vehicles being blown up. Near the start of the clip, the group’s black flag appears next to an American one. A message, in English, then flashes up: “We will drown all of you in blood.” A crude splatter of blood then appears on the U.S. flag to emphasize the point.

The militants have focused on territorial gains in parts of eastern Syria and northern Iraq, claiming them in its bid to establish a caliphate, or an Islamic state. But unlike al-Qaeda, which deemed this off-shoot too extreme, ISIS has not yet directly attacked the West.
