The attack by 10 anarchists on motor-bikes occurred at 6 a.m in the leafy Athenian suburb of Psychiko, according to Greek Reporter.
The assailants disappeared after the attack. No arrests have been made.
In a Facebook post, a spokesman for the group said that the attack was in response to Iran’s recent missile attack on a terrorist gathering in the Iraqi region of Kurdistan.
It came only two days after the country’s diplomatic mission in Paris was attacked by a group of individuals affiliated to the Komala terrorist grouplet.
The Komala is an Iraqi-based terrorist organization which has carried out assassinations in western Iran since the Islamic Revolution in 1979.
The Islamic Revolution Guards Corps on September 8 launched a missile attack on a center in the Iraqi Kurdistan Region that was used for training anti-Iran elements and hosted a meeting of terrorist leaders.
The terrorists had a role in the recent killing of Iranian soldiers at a border post in the western city of Marivan.
