Early in the morning on 12 March 2020, U.S. forces launched a series of airstrikes on the Imam Ali militant base in western Syria near the border with Iraq, killing at least 18 Iran-supported militants. The U.S. strikes were in retaliation for a rocket attack by unidentified militants linked to Iran on a joint base in Iraq on 11 March. In that attack, militants fired at least 20 artillery rockets at Camp Taji, a base in northern Iraq that hosts U.S. forces. The attack killed two U.S. soldiers and one British soldier; additionally, 12 other soldiers of various nationalities were wounded in the attack. No group has issued a claim of responsibility for the attack as yet.
