ATHENS – As anarchists are rampaging in Greece, an extreme-right alleged Neo-Nazi squad is believed behind the bombing of a squat in Piraeus occupied by far-leftists, with extremists on both sides of the spectrum engaging in battle.

Counter-terrorism officers are investigating the activities of five suspected neo-Nazis who were arrested over the bombing with sources telling Kathimerini they are believed members of the group called Apella which may be behind other politically-motivated attacks against the Left.

Greece is deeply polarized politically, with all 16 lawmakers from the ultra-far-right Golden Dawn and dozens of members on trial on charges of running a criminal gang and with clashes between the right and left having taken place before.

Raids on the homes of the suspects, all aged 18 to 26, turned up knives and other weapons as well as flags bearing the Nazi swastika, the paper said, although it wasn’t known if they are aligned with Golden Dawn or a radical offshoot although one Apella member was said to have previously been with Golden Dawn.

No one was injured in the blast at the Piraeus squat, which at the time had been organizing an event to commemorate the anniversary of the September 2013 killing of rapper Pavlos Fyssas in nearby Keratsini by a member of Golden Dawn who is out of jail because his 18-month detention period is up and the trial now in its third year showing no signs of coming to a finish.
