Athens - Greece's radical leftist group Revolutionary Struggle on Thursday claimed responsibility for a hand grenade attack on a police station in Athens last month and threatened to carry out more attacks. In a letter to satirical Greek weekly newspaper To Pontiki, the group said it was behind the attack, which caused minor damage and no injuries/
The group said its actions were in a response to police violence and threatened to escalate attacks if the Public Order Ministry does not change.
"We warn that if this climate of police violence and terrorism increases we will escalate our action accordingly," the group said in the four-page statement.
"Stop protecting rich thieves, criminal ministers and state officials," it demanded.
The statement was found in a rubbish bin outside an uninhabited house near central Athens and police are currently investigating its authenticity.
The group also claimed responsibility for a rocket-propelled grenade attack against the US embassy in January. The US government has offered a 1 million dollar reward for information leading to arrests.
No member of the group has ever been caught.
Greek anti-terrorist police were continuing their investigation into the embassy strike, seen as a symbolic attack against the most heavily-guarded building in the country.
The Revolutionary Struggle group first emerged in 2003 with a bomb attack on a courthouse and has become the country's most dangerous organization since the arrest of members of the deadly November 17 terrorist group prior to the 2004 Olympics in Athens.
The group has since claimed responsibility for an assassination attempt against Greece's culture minister in May of last year.
It staged similar attacks in June and December 2005 on the labour and economics ministries in Athens, injuring three people and causing extensive damage.
The economics ministry, located in the city's main Syntagma Square, approximately 100 metres from parliament, was closed at the time of the blast.
Anti-terrorism experts believe the group is composed of "a younger generation of terrorists" imitating the methods of the defunct Greek extremist organizations November 17 and the Revolutionary People's Struggle.
