Turkish news agencies say four policemen were killed and 14 people were wounded Thursday in an explosion near a bus terminal in the mainly Kurdish city of Diyarbakir. The state-run Anadolu Agency said a bomb detonated as a special forces vehicle passed by and that civilians were among the wounded. The private Dogan news agency reported the same toll and attributed the explosion to a car bomb. 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 in southeastern Turkey, which has suffered renewed violence between security forces and Kurdish militants. The blast damaged several cars and shattered almost all the windows of a high rise in the area. At least six ambulances deployed to collect casualties and security forces rushed to seal off the area. A military hospital where some of the wounded were reportedly taken declined to comment on casualties. Here are the latest updates: 9:05 pm: President Recep Tayyip Erdogan said this week that 355 members of the security forces had been killed in the fighting, along with 5,359 members of the PKK.
