The Supreme Court issued a request for red notices covering ex-prosecutors Zekeriya Oz, Celal Kara, and Mehmet Yuzgec, who are being sought over a 2013 plot by the Fetullah Terrorist Organization (FETO).

The fugitive suspects launched a so-called graft probe against top government officials on Dec. 17-25, 2013. The probe, including a large-scale raid and the detention of prominent figures, aimed to overthrow Turkey’s elected government.

 FETO and its U.S.-based leader Fetullah Gulen orchestrated the defeated coup 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.
