Reports say a crash involving a high-speed train at a station in the Turkish capital Ankara has killed at least nine people and injured 47.
Images from the scene showed emergency services working to rescue people from badly damaged carriages.
Reports citing local officials said the high-speed train had collided with another train, then into an overpass.
The accident occurred at about 06:30 local time (03:30 GMT).
The train was travelling from Ankara to the city of Konya in western Turkey.
The crash happened at the Marsandiz railway station, around 8km from Ankara’s main station.
The local governor’s office said the train driver was among the dead. Three of the injured are said to be in a serious condition.
A large number of emergency workers arrived at the scene shortly after the collision, which occurred in snowy conditions. Search and rescue efforts are under way.
In July, 24 people were killed in Turkey when a train travelling from the north-western town of Kapikuleen en route to Istanbul derailed.
