Iranian proxy militias have exchanged fire with U.S.-led coalition forces in eastern Syria, on Monday, after retaliatory U.S. airstrikes on the same militias in Iraq and Syria on Sunday night.

Following the U.S, airstrikes, the Iranian proxy forces had earlier vowed to retaliate. 

“U.S. Forces in Syria were attacked by multiple rockets. There are no injuries and damage is being assessed,” Col. Wayne Moratto, a spokesman for the U.S.-led mission Operation Inherent Resolve in Syria, posted on Twitter.

“U.S. Forces in Syria, while under multiple rocket attack, acted in self-defense and conducted counter-battery artillery fire at rocket launching positions,” Moratto added. The rockets hit the area at 7:44 p.m. local time.

The Syrian Observatory for Human Rights (SOHR), a U.K.-based watchdog of the Syrian Civil War, said Iranian-backed militias fired several shells at a U.S. base in eastern Syria’s Al-Omar oil field, also known as the “Green Village.” 

Only damage and no casualties were caused. Some rockets did land within the immediate vicinity of U.S. troops.

Syrian state news agency SANA said, “missiles… targeted a military base of the U.S. occupation forces in the Al-Omar oil field.” SANA did not cite who was responsible.

Nevertheless, an unnamed defense official told CNN that the rockets were likely launched by Iranian-backed militias operating in the immediate area near Deir Ezzor in eastern Syria.
