Fallout from collision that left 57 dead has put pressure on PM amid a growing belief of a cover-up by authorities

Hundreds of thousands of people have joined protests and strikes as Greece marks the second anniversary of a fatal train crash, the fallout of which has put the prime minister, Kyriakos Mitsotakis, in the line of fire.

As experts attributed the disaster to oversights and major systemic failures, striking workers grounded flights and halted sea and train transport, and rallies were held nationwide under the watch of police in riot gear. Banners in Athens’ central Syntagma square were emblazoned with the words: “Government of murderers.”
