A group of around 500 anti-establishment protesters marched in central Athens Tuesday, burning cars and destroying public property.
They marched toward Syntagma Square, which is close to the Greek parliament, and held banners that called for the immediate abolition of the anti-terror law.
Protesters are demanding the release of prisoners serving sentences for terrorism-related crimes, closure of high security prisons and changes to the country's anti-terror laws.
The march was then divided into two groups and one of them headed toward the Exarcheia area in central Athens.
Protesters then set fire to two cars outside the National Technical University of Athens and continued destroying public property.
Fire was also set to several garbage containers and the same group immobilized a bus driver and destroyed his vehicle.
Police forces were present but did not intervene.
