Riot officers fire teargas at hundreds of hooded youths as protests across Greece mark anniversary of Tempe disaster

Peaceful protests in central Athens have been eclipsed by the eruption of full-scale clashes between rock-throwing youths and riot police, as demonstrations and strikes were held across Greece to mark the second anniversary of a fatal train crash.

Thousands of people who had crammed into Syntagma Square for a demonstration later fled, some even seeking refuge in the parliament, as riot police fired rounds of teargas at hundreds of black-clad hooded youths lobbying rocks at them.
