At least 36 people were killed, and more than 85 others were wounded when two trains collided in northern Greece on Tuesday night, the Greek Fire Service says.
A spokesman, Vassilis Varthakogiannis, said in a televised briefing that a passenger train carrying more than 350 people collided with a freight train shortly before midnight local time in the area of Tempi, central Greece, near the city of Larissa.
The passenger train was traveling from Athens to Thessaloniki.
Rescuers are still in the process of identifying the dead, Varthakogiannis said in an updated briefing, adding that 150 firefighters and first responders are working on site.
As of now 66 people are being treated in hospital, with six in intensive care units.
The collision follows a nationwide carnival at the weekend which ended with a public holiday on Monday.
