A dozen ballistic missiles launched from outside Iraq have struck the country's northern Kurdish regional capital Erbil.
Kurdish officials said there were no casualties.
There was no immediate claim of responsibility or further details available. A U.S. State Department spokesperson called it an "outrageous attack" but said no Americans were hurt and there was no damage to U.S. government facilities in Erbil.
Iraqi state TV quoted the Kurdistan region's counter-terrorism force as saying 12 missiles launched from outside Iraq hit Erbil. It was not immediately clear where they landed.
U.S. forces stationed at Erbil's international airport complex have in the past come under fire from rocket and drone attacks that U.S. officials blame on Iran-aligned militia groups, but no such attacks have occurred for several months.
