Eight Turkish police officers were killed and 45 more people injured on Friday when a car bomb blamed on Kurdistan Workers' Party (PKK) militants exploded outside a police building in the southeast of the country.

The bomb attack caused immense damage to the headquarters of the special anti-riot police force in Cizre, with television pictures showing a thick plume of black smoke heading into the sky.

Eight police officers were killed and 45 more people wounded, two of them seriously, the state-run Anadolu news agency reported, quoting the local governorate.

Television quoted the health ministry as saying 12 ambulances and two helicopters had been sent to the scene.

Early pictures showed that the police building had been completely gutted by the power of the blast, reduced to a shell surrounded by a pile of rubble.

Adjacent buildings sustained severe damage and some were still on fire, television pictures showed.

Anadolu said the bomb had gone off 50 meters (yards) away from the building at a control post. It said the blast had been carried out by the PKK.

Security forces closed the main road to Cizre from the provincial capital of Sirnak to the north after the attack, Anadolu added.
