Reports state that several people have been wounded in the attack. No casualties have been confirmed yet.

The Diyarbakir governor's office said that the blast occurred during the repair of an armoured vehicle. The Turkish government apprears to have ruled out any foul play in the incident.

The blast comes a day before a Yes/No referendum vote in Turkey, where if voted 'Yes', the Turkish President Recep Tayyip Erdogan's presidential powers will be broadened.

The blast was reported in the residential district of Baglar, where a car bombing by suspected Kurdistan Workers Party (PKK) militants wounded scores of people last November.
