U.S.-backed forces foiled what would have been a “massive” suicide bombing attack on a “displaced persons” camp in Syria on Thursday.

Syrian Democratic Forces halted two vehicles full of ISIS terrorists strapped with explosives intending to detonate themselves inside the al-Hol refugee camp, according to U.S. CENTCOM.

The first vehicle prematurely detonated roughly 12 miles outside the camp, and SDF forces soon closed in and stopped the second vehicle.

“Two men exited the second vehicle wearing suicide vests. One detonated his vest. Syrian Democratic Forces shot and killed the second man. The second vehicle was rigged with at least 50 kilograms of explosives,” CENTCOM announced in a statement.

“By taking immediate action, and showing disregard for their own safety, the Syrian Democratic Forces demonstrated their professionalism and commitment to creating and maintaining a safe and prosperous region for the people who make it their home. The response of our partnered forces highlights not only dedication to their people, but also their tenacity and commitment to the enduring defeat of ISIS,” the statement continued.

CENTCOM says no SDF personnel were wounded in the operation.

The incident comes weeks after SDF rounded up dozens of ISIS terrorists working from inside the al-Hol camp in early September.

The SDF made the arrests in a series of operations throughout the camp, dissolving a network of terrorists operating there and elsewhere in Syria. ISIS terrorists have attacked American and allied targets throughout the summer.
