The protests were supported by demonstrations at more than 100 Greek embassies and consulates internationally, across all six inhabited continents.

Greece on Friday, the second anniversary of the deadly Tempi train crash, saw massive rallies and a general strike, bringing a halt to life across the country.

Riot police deployed tear gas and stun grenades to disperse a smaller group of protesters throwing Molotov cocktails and stones. Protesters have alleged that the government was involved in a cover-up of the deadly crash.
