An Ankara prosecutor has issued detention warrants for a total of 51 former public officials, including 27 ex-military officers over alleged links to Turkey’s Gulen group, which the Turkish government accuses of masterminding a coup attempt in 2016.

The group denies any involvement.

The Karar daily reported that following the warrants Turkish police has launched simultaneous operations in 19 provinces in an attempt to detain the targeted officials and army members.

The report said, among the suspects are 4majors, 1 lieutenant, 1 first lieutenant, 5 second lieutenants, 7 noncommissioned officers, 3 specialized sergeants, 3 colonels, 3 lieutenant colonel.

The military coup attempt killed 251 people and wounded more than a thousand others. Immediately after the abortive putsch, the Justice and Development Party (AKP) government along with President Recep Tayyip Erdoğan pinned the blame on the Gülen group. The group denies any involvement in the attempt.
