Two trains have collided in northern Greece, killing at least 36 people and injuring dozens of others, officials said Wednesday.
A passenger service carrying some hundreds of people crashed with a freight train on Tuesday night near the town of Tempe.
Multiple carriages derailed and the first two of the passenger train were almost completely destroyed after catching fire.
Rescuers have been working through the night at the crash scene with floodlights before dawn on Wednesday.
The head of a railway union has told the local media it is unclear what caused the collision, which is Greece's deadliest in recent years.
