Turkish police launched simultaneous operations after the Chief Prosecutor’s Office in Istanbul, the most populated city of Turkey, issued arrest warrants for 294 suspects for allegedly being involved in FETÖ’s infiltration into the Turkish Armed Forces (TSK).

Since May 2016, Turkey has classified the FETO organization as a terrorist organization under the assigned names Fethullahist Terrorist Organization and Parallel State Structure.

After the failed coup attempt in 2016, the government of Turkey blamed the group for the coup and authorities have arrested thousands of soldiers and judges who have links to the organization.
