Flights and rail services have been canceled, ferries halted and public transportation across the country has been severely disrupted. Private businesses and public services have also been affected, with many stores in Athens closed, leaving messages of solidarity for the victims’ families in front windows.

Riot police fired volleys of tear gas, stun grenades and water canon at protesters hurling gasoline bombs and smashed-up paving stones in Athens during mass demonstrations Friday to mark the second anniversary of a devastating train crash that has become a symbol of institutional failure in Greece.
