Greek police have clashed with hooded rioters as tens of thousands took to the streets of Athens on Wednesday.
Stones, bottles and petrol bombs were hurled at police, who responded with several rounds of tear gas.
The protestors were forced through Syntagma Square in front of parliament. Around 120 people have been detained.
The violence erupted after nearly 70 thousand people marched to parliament on the day of a general strike against a fresh round of cuts demanded by foreign lenders.
Much of the union anger is directed at spending cuts worth nearly twelve billion euros over the next two years.
Greece has promised the money to the EU and IMF in an effort to secure its next tranche of aid.
The bulk of the cuts is expected from wages, pensions and welfare benefits.
