Four U.S. troops were wounded in a raid that left an ISIS leader dead, according to CENTCOM spokesperson Col. Joe Buccino.
Hamza al-Homsi was the target of the raid. Military officials said he oversaw the group's terrorist network in eastern Syria.
Buccino said the four troops and a working dog were wounded when al-Homsi triggered an explosion during the raid.
No other ISIS fighters were killed or captured in Thursday night's raid, Buccino said. However, he noted that a separate raid on the same night resulted in the death of an ISIS assassination cell leader.
No civilians were injured in the operation, according to Buccino.
The U.S. has about 900 troops in northeast Syria. They are operating in areas controlled by Syrian Kurdish forces.
