Hulya Eroglu was in Interior Ministry's most wanted terrorists' list.
In a statement, the ministry said Hulya Eroglu, known also by her codename Gulbahar, was among the 31 terrorists killed during a counter-terrorism operation in Bestler-Dereler region of Sirnak province.
The operation had been ongoing since Nov. 2, the statement added.
Eroglu was said to be sole terrorist in the “red category” of the Turkish Interior Ministry’s list of wanted persons.
The Interior Ministry’s list is divided into five color-coded categories with red designated as the most wanted, followed by blue, green, orange and grey.
The PKK is listed as a terrorist organization in Turkey, the U.S., and the EU. In its over three-decade terror campaign against Turkey, more than 40,000 people have been killed.
Since the group resumed its armed campaign in July 2015, more than 1,200 people, including security force personnel and civilians, have lost their lives.
