A drone attack in Erbil, Iraq, or Wednesday targeted a Mossad hit squad, Iran’s official FARS news agency reported on Thursday.

According to Kurdistan’s counterterrorism service, three people were injured and several cars were damaged when an Unmanned Aerial Vehicle (UAV) detonated on the outskirts of the northern Iraqi city at approximately 9:30 p.m. local time.

Two security sources, speaking on condition of anonymity, said the drone had been shot down.

A security source said earlier that a drone attack had targeted the U.S. consulate in Erbil, but did not give further details.

Iraqi Prime Minister Mustafa al-Kadhimi told Kurdish Prime Minister Masoud Barzani in a phone call that Baghdad will cooperate with Erbil to hold the perpetrators accountable, according to a statement.

“Bomb-laden drone hit Erbil-Pirmam road, causing civilian injuries and damage,” the U.N. Assistance Mission for Iraq tweeted. “Iraq does not need self-proclaimed armed arbiters. Asserting State authority is essential. If the perpetrators are known, call them out and hold them to account.”

Last month, Iranian Islamic Revolutionary Guard Corps artillery fire hit an area north of Erbil, targeting what Iranian state television described as terror bases.

In March, the Guards attacked the capital of the Kurdish region with a dozen ballistic missiles in an unprecedented assault on the capital of the autonomous Iraqi Kurdish region. The IRGC later said it had targeted “a strategic center for conspiracy and mischiefs of the Zionists.”

Iraqi officials later said no evidence had been found of the Mossad maintaining a permanent base in Erbil.

At least three other attacks have targeted oil refineries in Erbil since the March attack, but no group has claimed responsibility for them.
