At least 10 people have been killed and more than 70 injured when a train derailed in Turkey.

Health ministry officials put the number of deaths at 10 and people injured at 73 based on initial reports from the scene, according to Turkey's official Anadolu news agency.

Five of the train's six cars were reported to have derailed in a village in Tekirdag province after "the ground between the culvert and the rail collapsed" in heavy rain.

The train was heading to Istanbul from Edirne, on the border with Greece, with 362 passengers and six crew members.

A survivor who was in one of the carriages that derailed told the DHA news agency: "There were deaths immediately and people whose legs were crushed. It was a horrible accident."

Cars were photographed overturned and several people carried away on stretchers.

Tekirdag governor Mehmet Ceyhan said the area where the derailment happened was muddy from heavy rain and difficult to reach.

Emergency services and military helicopters rushed to the scene.

Local officials tweeted that hospitals needed blood donations for the injured.
