A radical left-wing group in Greece has claimed responsibility for the December attack on the Israeli Embassy in Athens.

An organization called Group of Popular Rebels said it committed the attack, Greek police said Wednesday, according to The New York Times, which cited an unnamed police official. Gunmen opened fire with Kalashnikov rifles on the embassy, damaging the building but causing no injuries.

The claim came in a 19-page statement found by police on a portable digital storage device left in a trash bin in southern Athens, according to the newspaper.

The two rifles used in the embassy shooting spree were used in a similar attack in December 2013 on the German ambassador’s home in the Greek capital.

Greek anarchist groups have attacked several foreign embassies in Athens in recent years.
