WASHINGTON — U.S. forces attacked nine Iran-backed targets in Syria over the weekend in response to two strikes on U.S. troops, the Pentagon said Tuesday.

“These [U.S.] strikes will degrade the Iranian-backed group’s ability to plan and launch future attacks on U.S. and coalition forces who are in the region to conduct defeat ISIS operations,” said Air Force Maj. Gen. Pat Ryder, top Pentagon spokesman.

The U.S. forces were attacked Sunday at Mission Support Site Green Village in Syria in two separate attacks within 24 hours. One attack was with a drone and the second was indirect fire from two rockets.

There were no injuries to U.S. troops. Ryder was unable to provide details on any damage to the installation as a result of the attacks.

Ryder declined to say which Iranian-proxy groups were associated with the attacks or what sites U.S. forces attacked in response.

The exchange of strikes was first announced Monday by U.S. Central Command, which oversees military operations in the Middle East.

“Our message is clear. Attacks on U.S. and coalition partners in the region will not be tolerated,” Army Gen. Michael Erik Kurilla, commander of CENTCOM, said in a social media post.

The U.S. has about 900 personnel in Syria to assist partnered forces in conducting missions against Islamic State militants. In February, U.S. forces launched an attack on Iranian-backed militia sites in Syria in response to a drone attack in Jordan that killed three U.S. service members.

Since the Oct. 7 attack by Hamas militants in Israel and Israel’s war in Gaza in response, Iran-backed fighters who are loosely allied with Hamas have carried out drone and rocket attacks on bases housing U.S. troops in Iraq and Syria.
