At least four people were dead, six were injured when a passenger train derailed in northern Greece on Saturday night, fire brigade and police officials said.
Photographs on Greek news websites showed one carriage on its side near a residential area.
The train was heading from Athens to the second biggest city Thessaloniki in northern Greece when it derailed near the town of Adendro. Its engine was propelled into a nearby house but the cause of the accident was not yet known, a police official said.
The Athens News Agency reported about 100 passengers were on board the train and some media said five carriages had derailed.
Twelve fire brigade trucks were deployed to the area, the fire brigade said and a rescue operation was under way.
