Four PKK terrorists surrendered to security forces in Turkey's southeastern province of Şırnak, the Interior Ministry said in a statement on Thursday.
Terrorists, including a woman, surrendered at Habur border gate, the statement added.
Turkey has "neutralized" 635 PKK terrorists in some 81,000 anti-terror operations since the start of 2019, the country's interior minister said on Thursday.
In its more than 30-year terror campaign against Turkey, the PKK -- listed as a terrorist organization by Turkey, the U.S. and the EU -- has been responsible for the deaths of nearly 40,000 people, including women, children and infants.
