A Turkish judge has been sentenced to seven years in prison for being a member of the Gülenist Terror Group (FETÖ), the group Ankara has accused of being behind last July's coup attempt, a judicial source said Wednesday.

Ankara's 16th High Criminal Court sentenced Aydın Sefa Akay — who was involved in a U.N. panel hearing for the Rwandan genocide case — to seven years and six months in jail, the source said on condition of anonymity due to restrictions on talking to the media.

Akay was remanded last year as part of a FETÖ probe in the aftermath of the failed coup attempt and denied the accusations, demanding an acquittal during the hearing.

The court also ruled Akay be released under judicial supervision and be banned from traveling abroad until the sentence was declared final.

According to the Turkish government, FETÖ and its U.S.-based leader Fetullah Gülen orchestrated the attempted coup in July 2016, which left 250 people killed and nearly 2,200 injured.

Ankara has accused FETÖ of being behind a long-running campaign to overthrow the state through the infiltration of Turkish institutions, particularly the military, police and judiciary.

Since the defeated coup attempt, operations have been ongoing in the military, police and judiciary, as well as in state institutions across the country, to arrest suspects with alleged links to FETÖ.
