The U.S. military said Monday a "helicopter mishap" in northeastern Syria injured 22 service members.
U.S. Central Command said in a statement there was no enemy fire reported and the cause of the incident was under investigation.
It said 10 of those injured were taken for treatment at higher-care facilities outside of the region overseen by CENTCOM, which stretches from Egypt to Kazakhstan.
The United States has about 900 troops in Syria as part of a mission to advise and assist partners in the fight against the Islamic State group.
