Iran's Revolutionary Guards claimed responsibility for a dozen ballistic missiles that struck Iraq's northern Kurdish regional capital of Hewler (Erbil) in the early hours of Sunday, Iran's state media reported, adding that the attack was against Israeli "strategic centres" in Erbil.

The missiles, which targeted the U.S. consulate's new building, caused only material damage and one civilian was injured, the Kurdish interior ministry said. An Iraqi security official told Reuters that the missiles were manufactured in Iran.

"Any repetition of attacks by Israel will be met with a harsh, decisive and destructive response," the Revolutionary Guard said in a statement reported by state media.

A U.S. official blamed Iran for the attack earlier on Sunday but did not give further details. Iranian officials have yet to comment.

Separately, 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.

U.S. forces stationed at Erbil's international airport complex have in the past come under fire from rocket and drone attacks that Washington blames on Iran-aligned militia groups, but no such attacks have occurred for several months.

"It’s premature to point the finger of blame at a specific party but initial reports show indisputably that it was a cross-border short range missile attack," an Iraqi security official, who spoke on condition of anonymity, said.

"Parts of the fired missiles were retrieved and it was manufactured by Iran," he said.
