The human cost of the spiralling violence is beginning to be felt in Turkey.
Relatives have gathered to mourn a soldier killed when militants attacked a military base in Sirnak on Monday.
The sorrowful scene is being repeated elsewhere. The victim was one of at least nine people who died on Monday in a wave of attacks on the security forces.
Recep Tayyip Erdogan says his government will not rest until the terrorist threat is eradicated:
“Preventing guns being fired is not enough,” the Turkish President said in a speech. “Weapons should be put down and buried. I insist on this. Our fight will continue until not one terrorist is left within our borders and their weapons have been covered with concrete.”
The US Consulate in Istanbul opened its doors to the public a day after a gunfight between police and militants.
The Kurdish PKK has said it was behind the separate bombing of a police station nearby in which four people died.
Air strikes continue
Military activity in the region is intense.
Planes leave for a fresh round of air strikes in the south eastern province of Hakkari, while the US-led coalition pursues an air campaign against Islamic State in Iraq.
Prime Minister Ahmet Davotoglu has told the BBC Turkey is still in favour of a no-fly zone to protect civilians in Northern Syria.
