The pore-dawn attack damaged a hangar, tweeted coalition spokesman Col. Wayne Marotto. He said the attack was under investigation. An Iraqi military statement also said no losses were reported.
Drone strikes are less common. In mid-April, an explosive-laden drone targeted the military section of the international airport in Irbil, in Iraq's northern Kurdish-run region, causing no casualties or damages. The base also hosts U.S. troops.
The attacks have been frequent since a U.S.-directed drone strike killed Iranian General Qassem Soleimani near the Baghdad airport last year. Iraqi militia leader Abu Mahdi al-Muhandis was also killed in the attack. The strike drew the ire of mostly Shiite Iraqi lawmakers and prompted parliament to pass a non-binding resolution to pressure the Iraqi government to oust foreign troops from the country.
