A police station west of Athens came under firebomb attack early Thursday, police said, leaving several vehicles damaged but causing no injuries.
A group of youths drove past the police station in the Perama district, about 20 kilometers west of the Greek capital, throwing several firebombs at the building, police said.
The pre-dawn attack burned three police cars and a motorbike, and one unmarked police car, authorities said.
Anarchist groups have been blamed for similar attacks over the past few years in Athens and Thessaloniki, Greece's second-largest city. They regularly target banks, government buildings and vehicles and car dealerships, as well as police stations.
