A Greek far-left armed group claimed responsibility on Wednesday for two bomb attacks which caused minor damage, but no casualties, outside a prison and inside a courthouse last week, police said.
Greece has experienced a wave of unrest since 2008 that has gained momentum in the last month with large-scale protests against government austerity measures prescribed by the European Union and the International Monetary Fund in return for aid.
The demonstrations turned violent on May 5 as far-left and anarchist groups on the fringes of the protests clashed with police and attacked businesses. Three bank workers, including a pregnant woman, were killed when their bank was set ablaze.
A number of small militant groups have also carried out minor bomb attacks in Athens and the second city Thessaloniki.
The Fire Conspiracy Cells group sent a statement to a website saying they carried out Thursday's bomb attack on Athens' main prison and a second blast in the toilets of a courthouse in Thessaloniki on Friday.
Police said they were investigating the claim.
The group said the attacks were aimed at weakening the government as it attempted to implement its "new economic measures".
The Greek government has cut extra salary payments to civil servants and raised taxes in order to reduce its bulging deficit and help fight its way out of a debt crisis that has also destabilised other euro zone economies.
