BAGHDAD — Three booby-trapped drones hit on Tuesday a US-led coalition base in Erbil airport, located in northern Iraq's semi-autonomous region of Kurdistan.

Two drones, which attacked the base in the morning, were shot down in the airport area, and a third drone crashed and failed to explode in the same area, the regional Kurdistan Counter-Terrorism Service said in a statement without revealing casualties.

Separately, an unnamed Kurdish security source told Xinhua that the US anti-aircraft weapons shot down two of the drones.

Later in the day, an armed group calling itself the "Islamic Resistance in Iraq," which is an umbrella body for Iranian-backed Iraqi militias, claimed responsibility for the drone attacks, saying its fighters launched two drones toward a US military base and hit their targets.

The group provided no further details about the third drone in its brief statement.
