Gunmen attacked a police station in Athens today but there were no casualties, police said.
The police said they suspected the attack in the western suburb of Korydallos was linked to Greece's most violent guerrilla group, the left-wing Revolutionary Struggle.
"Shots were fired and a hand grenade was thrown at the police station, but no one was injured," said a police official, declining to be named.
At least three assailants were involved in the attack, with two using automatic weapons and a third throwing the grenade, which failed to explode, before making their escape, police said.
"About 16 9-millimeter shell casings, probably from an MP5 automatic weapon, were found and are being examined at the lab," the police official said. "The incident is being investigated by the counter-terrorism police."
Police also said that a phone call was made to daily Ta Nea newspaper soon after the attacks with the caller claiming responsibility on behalf of Revolutionary Struggle, but they could not immediately confirm its validity.
Police are now checking video footage from closed circuit cameras in the area and will also check footage from bank cameras that may show the attackers on their way to or from the attack, the official said.
The incident occurred one month after a policeman was seriously wounded when police were attacked with semi-automatic weapons in central Athens.
That attack took place in the area where the killing of a 15-year-old boy by a policeman on December 6 sparked the worst riots in Greece for decades. Revolutionary Struggle claimed responsibility for the attack.
After the capture of the November 17th leftist guerrilla group in 2002, Revolutionary Struggle emerged and launched a series of attacks that included a rocket-propelled grenade strike against the US embassy in Athens in January 2007.
