The troubles were sparked when a 15-year-old boy was killed by a police bullet on December 6.
At Athens University rioters hurled rocks and petrol bombs from the roof, safe in the knowledge that the police are banned from entering the building under Greek law.
Hospitals, schools and transport have been disrupted as angry workers have walked off the job, furious at the level of poverty in Greece, and government reforms to education and pensions.
Retailers closed their doors and Christmas shoppers were sent running for cover as the scuffles spilled over again into the heart of Athens.
Riot-squads and fire-fighters scrambled to save the city’s main Christmas tree from being torched, just a week after the one it replaced was burned down in the disturbances.
