WASHINGTON (Reuters) -Twenty-two U.S. service members were injured in a helicopter "mishap" in northeast Syria on Sunday, the U.S. military said late on Monday, without disclosing the cause of the incident or detailing the severity of the injuries.
The U.S. military's Central Command said 10 service members were evacuated to higher-level care facilities outside the region.
Central Command, which oversees U.S. troops in the Middle East, said no enemy fire was reported but added that the cause of the incident was under investigation.
Officials at U.S. Central Command did not immediately respond to requests for further information.
The U.S.-backed Syrian Democratic Forces, which control swathes of northeast Syria, referred questions to the U.S.-led coalition under which American troops are deployed in the zone.
