A Greek militant anarchist group has claimed responsibility for a gunfire attack on the Israeli embassy building in Athens last year that caused no injury and minor damage.

Police said Wednesday a proclamation by the "Group of Popular Fighters" over the attack early on Dec. 12 was found in an Athens rubbish bin, following a phone call to a newspaper.

Authorities had already linked the group to the Israeli embassy hit, in which more than 50 bullets from assault rifles were fired at the building's facade before it opened for business. Ballistic tests had shown that the weapons had also been employed in a similar shooting, claimed by the "Group of Popular Fighters" outside the German ambassador's residence in Athens in 2013.

Nobody has been arrested for either shooting.
