An armed drone on Friday hit Iraq's al-Harir airbase, where US and international forces are stationed, Iraqi Kurdistan's counter-terrorism service said.
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 US military carried out a retaliatory strike in Baghdad that killed a militia leader it blames for recent attacks on US personnel, the Pentagon said.
Since the Israel-Hamas war in the Palestinian territory of Gaza began in October, the US military has come under attack at least 100 times in Iraq and Syria, usually with a mix of rockets and one-way attack drones.
