“A helicopter mishap in northeastern Syria resulted in injuries of various degrees to 22 US service members” on Sunday, Centcom said in a statement.
“The service members are receiving treatment for their injuries and 10 have been evacuated to higher care facilities,” it said.
“The cause of the incident is under investigation, although no enemy fire was reported.”
As part of global efforts to combat terrorists, the United States maintains around 1,000 troops stationed in Syria and occasionally launches airstrikes that target militants there.
Over the past year, US bases have been routinely attacked, with cells connected to the Islamic State organization claiming credit for some of them.
After a US contractor was killed in a drone attack on a US-led coalition base close to the city of Hasakeh in northeastern Syria, the US launched airstrikes on Iran-linked groups in Syria in March.
At the time, the war monitor Syrian Observatory for Human Rights said that the US airstrikes had resulted in at least 19 fatalities.
