At least eight police officers have been killed and 45 wounded in a truck bomb attack at a police headquarters in Cizre in southeastern Turkey, according to Turkish media.
The attack on Friday was followed by an armed battle between the police and attackers.
Ambulances, including helicopters, have been sent to the scene, television channels said. They also showed live footage of smokes rising from the building and rubble left from the building.
Cizre is in Sirnak, a province that borders both Syria and Iraq and has a largely Kurdish population.
State media blamed the Kurdistan Workers’ Party (PKK) rebels for the attack.
The PKK, an armed group seen as a terrorist organisation by Turkey, the US and the EU, has recently stepped up its attacks in southeastern Turkey.
The region is going through the most intense fighting in decades after a ceasefire between the Turkish state and the PKK collapsed in July last year.
