American and Syrian forces came under fire on Saturday during a joint patrol near the ancient city of Palmyra, according to the Syrian state news agency SANA.
At least two members of the Syrian security forces were wounded, while several U.S. forces were injured, the agency said, citing a security source.
Spokesmen from the Syrian Ministry of Interior and U.S. Department of Defense did not immediately respond to requests for comment. The New York Times could not independently verify details of the attack.
A gunman who attacked Syrian and American forces was killed, according to the news agency, though details about the individual’s identity or motives remain unclear.
The Syrian Observatory for Human Rights, a monitoring group, also reported a similar attack on Syrian and American forces.
The attack comes amid continuing shifts in the security dynamics in Syria. The United States has in recent months been drawing down its troops from the country, a reflection of the evolving situation after the ousting of the dictator Bashar al-Assad last December.
