rocket attack targeting the base killed a U.S. civilian contractor and wounded several American and Iraqi personnel. The attack was suspected to be conducted by Iran-backed militants of Kata'ib Hezbollah. That led to retaliatory airstrikes conducted by United States in Iraq and Syria, killing 25 Kata'ib Hezbollah militiamen. The United States Army left the air base on March 29, 2020.
