Police officer dies after car bomb attack, raising death toll to six
A police officer wounded in a suicide car bombing in a town near Turkey's border with Syria has died in hospital, raising the death toll to six, Turkish media said.
Turkish authorities said the attack which targeted the police headquarters in Midyat, in Mardin province, was carried out by militants of the outlawed Kurdistan Workers' Party, or PKK.
Two women police officers were among the dead.
Anadolu Agency said a third police officer, who was seriously wounded in the attack, died at a military hospital in the city of Diyarbakir on Thursday.
The PKK has targeted police and military personnel since July, when a fragile peace process between the rebels and the government collapsed.
The group is considered a terror organisation by Turkey and its allies.
Earlier on Tuesday, suspected Kurdish militants exploded a car bomb in Istanbul as a police bus was passing by, killing six police officers and five civilians.
Turkey's agriculture minister has since said the sale of fertilisers containing nitrate has been temporarily suspended throughout the country following the back-to-back car bombings.
Faruk Celik told state television on Thursday: "As of now, the sale of fertilisers containing nitrate that are used for explosives has been frozen in Turkey."
Turkey had already taken measures to control and track fertilisers sales but Mr Celik said those measures were insufficient.
Mr Celik said security officials have seized 64,000 tons of fertiliser from retailers.
