Many people have been wounded in a car bomb attack at a police headquarters in Cizre in southeastern Turkey, according to the Turkish media.
The attack on Friday was followed by an armed battle between the police and attackers.
There were no immediate details on casualties, but ambulances have been sent to the scene, television channels say. They also showed live footage of smokes rising from the building.
Cizre is in Sirnak, a province that borders both Syria and Iraq and has a largely Kurdish population.
