A drone loaded with explosives hit Erbil International Airport late on Wednesday night. The Ministry of the Interior of the South Kurdish regional government said the attack was directed at the international coalition fighting ISIS. There were no reports of casualties, said ministry officials.

The drone was loaded with TNT. The coalition said a fire broke out on the roof of a hangar. The attack is being investigated.

Both Iranian-backed Shiite militias and ISIS are eligible for the attack. The last time the Saraya Awlia al-Dam group attacked Hewlêr airport with rockets was in February. This previously unknown group is said to be an Iranian proxy militia.
