Four police officers have been killed in a bomb blast that rocked the Kurdish-dominated south-eastern Turkish city of Diyarbakir.
At least 14 people were injured in the explosion near a bus shelter, security sources said. It is not known who was behind the blast.
Turkey’s army is locked in an operation against rebels from the Kurdistan Workers Party (PKK) in the region.
A ceasefire between the government and the PKK collapsed in July last year.
Since then violence has surged, with militants attacking security forces and the army besieging Kurdish-dominated towns.
The bomb reportedly detonated as an armoured police vehicle drove past.
Pictures on social media showed debris strewn across the ground and ambulances at the scene.
