Three drones targeted a military base at Arbil airport in Iraqi Kurdistan on Tuesday. The base plays host to troops from the US-led coalition, local officials said.
On Tuesday morning, "at two different points, three drones attacked the international coalition," the anti-terrorism service of the autonomous region of Kurdistan said in a statement.
In the first attack on the military base, two drones were shot down. Subsequently, a third drone crashed to the ground without exploding, according to the statement.
An official in the US Department of Defense told AFP under condition of anonymity that according to the latest information, the attack had led to "no casualties or damage to infrastructure."
Following the outbreak of the Hamas-Israel war last month, a series of rocket and drone attacks have targeted military bases hosting US and coalition forces in Iraq and Syria.
Since Oct. 17, US and coalition forces in Iraq and Syria had been targeted by drone or rocket attacks 38 times, injuring 45 US personnel, according to the Pentagon.
Tuesday's attack on the base at Arbil airport was claimed by a group known as "Islamic Resistance in Iraq" on Telegram channels affiliated with Iraqi factions close to Tehran. The same group has claimed most of the recent attacks.
In a visit to Baghdad on Sunday, US Secretary of State Antony Blinken said the attacks, which Washington has linked back to Iran, were "totally unacceptable."
Some 2,500 American troops are deployed in Iraq and another 900 in Syria, as part of the international coalition that was established in 2014.
In Iraq, the coalition says its role is limited to advising and supporting local counterparts.
