One soldier was martyred Sunday in a PKK terror attack in Turkey's southeastern Hakkari province, according to security sources.

From the Iraqi border, the PKK terrorists attacked a military base in the province's Çukurca district, said the sources who spoke on condition of anonymity due to restrictions on speaking to the media.

A 21-year-old soldier was wounded in the attack and later succumbed to his wounds at Hakkari State Hospital.

Anti-terror operations are ongoing in the province, the sources added.

Since the PKK launched its terror campaign in 1984, an estimated 40,000 people have been killed in Turkey in related violence.

Following a brief reconciliation period, the group resumed fighting in July 2015.

Since then, it has been responsible for the deaths of approximately 1,200 security personnel and civilians, according to an official tally, while more than 4,000 security personnel and over 2,000 civilians have been injured.
