Violence erupts in Greek cities

A protest through central Athens to mark the anniversary of the fatal police shooting of an unarmed teenager quickly turned violent as marchers damaged shopfronts and bus stations and set fire to looted clothes.

Clashes continued late into the night in the neighbourhood of Exarchia, a haven for extreme left-wingers and anarchists, with youths ambushing police forces with firebombs and rocks thrown from balconies.
