The attack targeted the Mermer gendarmerie station yesterday on a highway near the mostly-Kurdish town of Lice and touched off clashes between the soldiers and rebels of the outlawed Kurdistan Workers' Party, or PKK, according to the state-run Anadolu Agency.
It said ambulances were dispatched to the area.
The private Dogan news agency said some soldiers were wounded in the attack, adding that the military sent reinforcements to the area.
A fragile peace process between the PKK and the government broke down in July, leading to renewed violence between the rebels and the Turkish security forces. The conflict has killed hundreds of people, including more than 300 police officers and soldiers.
