An armed drone on Friday hit Iraq's al-Harir airbase, where U.S. and international forces are stationed, Iraqi Kurdistan's counter-terrorism service said, Paralel.Az reports citing Reuters.

A service statement did not elaborate on whether the attack caused casualties or infrastructure damage.

A group called the Islamic Resistance in Iraq said it had attacked al-Harir military base by drone.

Friday's action took place a day after the U.S. military carried out a retaliatory strike in Baghdad that killed a militia leader it blames for recent attacks on U.S. personnel, the Pentagon said.
