At least four policemen were killed in a bomb blast Thursday afternoon in Diyarbakir province in southeastern Turkey, Anadolu Agency reported. As many as 14 people were also injured in the bomb attack.

The injured included eight police personnel and six civilians. Three of the injured policemen were seriously injured, Agence France-Presse quoted a source as saying. 

The bomb went off when a police service vehicle was passing through the intercity bus terminal in Baglar district of the province, sources told AA. The explosion caused damage to cars and buildings nearby.

The bomb attack took place a day before Prime Minister Ahmet Davutoglu's visit to Diyarbakir.

Rebels, mainly from the Kurdistan Workers Party (PKK), have been targeting the Turkish regime forces and the Army since July last year. The constant confrontation between the two sides have led to hundreds of casualties.

At least 355 security personnel and as many as 5,359 PKK rebels have been killed so far, AFP quoted President Recep Tayyip Erdogan as saying.
