On Feb. 28, 2023, a passenger train and freight train collided, leaving 57 dead. New evidence suggests many may not have been killed by the crash itself, but by a fire that followed.

Greece is expected to come to a standstill Friday with sweeping strikes and protests to mark the second anniversary of the country's worst rail tragedy, that left 57 dead in 2023.

Two years after the head-on collision of two trains that killed 57, people in Greece are still demanding justice for the victims of the crash. A general strike and demonstrations are planned for Friday.
