Turkish prosecutors issued detention warrants for 37 suspects over their alleged links to the FETÖ, the group behind the 2016 defeated coup attempt, state-run Anadolu Agency said on Feb. 25.
Authorities in the central Konya province issued detention warrants for the suspects, some of whom are active-duty soldiers in the Turkish Armed Forces (TSK).
The suspects were accused of allegedly serving as FETÖ's "covert imams" - senior members of the terror group - the news agency cited anonymous sources as saying.
Police have launched simultaneous operations across 24 provinces.
FETÖ and its U.S.-based leader Fetullah Gülen orchestrated the defeated coup attempt of July 15, 2016, which left 251 people killed and nearly 2,200 injured.
Ankara accuses FETÖ of being behind a long-running campaign to overthrow the state through the infiltration of Turkish institutions, particularly the military, police and judiciary.
