Police arrested more than 30 military officers for alleged links with the Fetullah Terrorist Organization (FETO) during an operation based out of southeastern Siirt province Tuesday, according to a police statement.
The operation was carried out across 20 provinces.
The 31 suspects, which included four majors, two lieutenants, a first lieutenant, 15 sergeants and 7 specialized privates, were later remanded in custody.
FETO and its U.S.-based leader Fetullah Gulen orchestrated the defeated coup attempt of July 15, 2016, which left 250 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.
