A gang of mostly hooded youths on Saturday attacked the exterior of the Exarchia police precinct in downtown Athens. The hoodlums threw firebombs at the precinct's entrance and fled.
Two police cars which were parked outside the station were torched and a nearby flower peddler suffered burns.
The Exarchia district has long been a hub of self-styled anarchist and so-called "anti-state" activists, mostly teenagers and young people.
In a separate incident early Saturday morning, unknown individuals threw firebombs at ruling PASOK's offices and against riot police stationed nearby.
No injuries were reported.
