A car bomb blast has hit police headquarters in south-eastern Turkey, killing six people and wounding at least 39.

Five civilians including a baby were among the dead, while rescuers searched the rubble for survivors at the scene in Cinar district, Diyarbakir province, BBC says.

Officials said Kurdistan Worker’s Party (PKK) militants are responsible for the attack, but no group has claimed responsibility.

The explosion caused damages to nearby residential buildings, where a mother and her five-month-old baby were killed and a girl aged one and a five-year-old boy also died when a house collapsed.
