Clashes erupt at protest over train crash in Greece

STORY: The rally was one of several since the train crash on February 28, where 57 died. Unions called a general strike, halting transport at ports, airports, bus, train and railway stations.

Protesters accuse the conservative government and the country's political system of ignoring repeated calls by unions over deficient safety measures.

More than 25,000 people rallied in central Athens, according to police estimates, and protests were also held in other Greek cities.

Prime Minister Kyriakos Mitsotakis, whose term ends in July, has apologized over the crash, promised to hire more staff and to fix the rail sector with support from the European Union.
