Police arrested four suspects for alleged links to the Fetullah Terrorist Organization (FETO), the group behind the 2016 defeated coup, security sources said Wednesday.
The Samsun-based operations were carried out across three provinces and nabbed the suspects, including active-duty, retired military personnel and dismissed soldiers.
The suspects are accused of communicating by payphone with "covert imams” who are senior FETO members.
FETO and its US-based leader Fetullah Gulen orchestrated the defeated coup of July 15, 2016, which left 251 people martyred and nearly 2,200 injured.
Ankara also 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.
