A group not known to police claimed responsibility for two early morning arson attacks in Athens — on a Finnish diplomat’s car and an office of the ruling New Democracy party — in which nobody was injured.

A man claiming to be from a group called “Anti-State Justice” rang Alter television station and said the organization had conducted the attacks, which resulted in damage to buildings and several cars.

The first raid took place at 3.10 a.m. in Mets, near the city center, when a gas canister device exploded under an apartment block where several cars, including the diplomat’s, were parked. Police do not think the diplomat was the target of the attack.

Just over an hour later, a similar homemade device went off outside the entrance to an ND office in Kypseli, near central Athens. The party office was housed in the ground floor of an apartment block but none of the homes in the building was affected by the fire that broke out.

The group said the attacks were in support of three suspected anarchists who were arrested in July on suspicion of having attacked policemen and stolen their equipment.
