A bomb detonated near a bus shelter has rocked the Kurdish-dominated south-eastern Turkish city of Diyarbakir, security sources say.
At least seven people were injured in the blast as an armoured police vehicle drove by, the sources added. It is not known who was behind the explosion.
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.
Pictures on social media showed debris strewn across the ground and ambulances at the scene.
Three of those wounded were members of the Turkish security forces, a source told the AFP news agency.
