SIRNAK, Turkey 

Turkish security forces arrested 26 people for their suspected links to the PKK terror group and the Fetullah Terrorist Organization (FETO) in southeastern Turkey, security sources said on Monday.

Local counter-terrorism police in the Sirnak province nabbed suspects during anti-terror operations held on Aug. 10-16, said the sources who asked not to be named due to restrictions on speaking to the media.

The suspects were sent to a local courthouse which released 13 of them. The legal procedures continue for the remaining suspects.

FETO and its US-based leader Fetullah Gulen orchestrated the July 15, 2016 defeated coup in Turkey, in which 251 people were martyred and nearly 2,200 injured.

Ankara accuses FETO of being behind a long-running campaign to overthrow the state through the infiltration of Turkish institutions, particularly the military, police and judiciary.

In its more than 30-year terror campaign against Turkey, the PKK -- listed as a terrorist organization by Turkey, the US, and EU -- has been responsible for the deaths of 40,000 people, including women, children and infants.
