The airport is used as a base for US-led coalition forces.
The incident attracted attention when a large mushroom-shaped cloud of smoke rose over Erbil.
According to local Kurdish media, it was the US-led force that detonated a bomb in the area.
The force, which was formed to fight the terrorist group ISIS, is expected to complete its withdrawal from Iraq by the end of the month. The coalition has already left other bases in Iraq and remains only at the airport in Erbil.
