Greek police have fired tear gas to disperse farmers protesting against pension reforms in central Athens.
Farmers from all over Greece were heading to the capital to demonstrate their fury at the government's plans to raise pension contributions and taxes.
About 800 farmers from Crete, Greece's biggest island, scuffled with police guarding the entrance to the ministry, throwing stones and breaking windows.
"The farmers attempted to push the police in front of the ministry's entrance. The police used tear gas to stop them," a police official said.
