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

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.

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.
