An ISIS official who was involved in planning prison breaks of extremists in Syria was killed during a raid by U.S. and coalition forces last week, CENTCOM announced on Wednesday.
Multiple weapons, ammo, and a suicide belt were also seized during the raid on Feb. 10.
Officials did not release the exact location of the raid or whether there were casualties besides the death of Ibrahim Al Qahtani.
More than 10,000 ISIS fighters are detained in northeastern Syria, including 5,000 Syrians, 3,000 Iraqis, and 2,000 extremists from outside those two countries, according to the State Department.

Prison breaks have long been a key strategy for extremist movements in the Middle East to sustain their forces.
"ISIS knows that prison breaks work. They are time tested and generate results," Ian Moss, the Deputy Coordinator for Countering Violent Extremism and Terrorist Detentions, said at a briefing in October.
"So far, we have prevented ISIS from freeing these fighters. But there are a range of detention facilities in northeast Syria, and we know they will try to attack them again."
About 900 U.S. troops are still in Syria to help the Syrian Democratic Forces and other coalition groups suppress ISIS.
