Thousands of protesters took to the streets of Athens and Thessaloniki to mark the anniversary of the 1973 crackdown on a student uprising against the military dictatorship then ruling Greece.
Hundreds of youths attacked police, hurling rocks, flares and gas bombs following large and peaceful marches to mark the 1973 anniversary. Protesters also hurled dozens of petrol bombs as they confronted police in narrow streets in the heart of the city. Police fired tear gas at the protesters.
In Thessaloniki, a motorcycle driver was taken to hospital after driving into a barricade set up by protesters.
