A small group of protesters threw petrol bombs at police officers in front of the Greek parliament ahead of Wednesday night’s key vote on further economic reforms.
Until then the rally had been largely peaceful.
Witnesses said the disturbances were due to a few dozen anarchists .
The unrest came after a day of marches organised by the Communist Party and public sector workers.
Our reporter Michalis Arampatzoglou was there:
“Thousands of people that have demonstrated tonight at Syntagma Square against austerity, and have decided to continue the protests over the coming weeks.”
Earlier thousands had carried their anti- austerity message through the streets of Athens.
One woman urged parliament to reject the second raft of reforms:
“We are protesting against the measures that are being voted on today in the Parliament. We are demanding MPs should vote down the measures. We are fighting so that the third memorandum doesn’t pass, because we believe that it’s a disaster. In reality it’s blackmail. The crisis will be paid for again by the unemployed, the workers and the young. We want this to stop”
But inside Parliament lawmakers were being faced with tough new reforms needing approval before negotiations for a third international bailout can begin.
