Turkish news agencies say an explosion went off near a bus terminal in the mainly Kurdish city of Diyarbakir in the southeast of the country. The government put the initial toll of wounded at 14.

The state-run Anadolu Agency said a large number of ambulances were deployed to the scene.

The private Dogan news agency said a car bomb targeted a bus transporting police. The agency blamed "terrorists" for the incident, using the government designation for Kurdish rebels.

An opposition politician based in Diyarbakir, Omer Tastan, confirmed there had been an explosion in the city, which has suffered renewed violence between security forces and Kurdish militants.
