Greece train crash: Protesters and police fire petrol bombs, tear gas amid Athens rally clashes

Clashes broke out in Athens on Sunday between police and a group of demonstrators over a train crash in Greece earlier this week that killed at least 57 people. University students and railway workers protested on Syntagma Square in central Athens over the accident, the deadliest in Greece’s living memory. Video shows demonstrators hurling objects including petrol bombs at riot police, as authorities moved in to contain the unrest, and police responded with volleys of tear gas.
