A Turkish man who has been in solitary confinement for over 20 months over links to the Gülen group, has suffered from severe facial paralysis, journalist Sevinç Özarslan reported.

Akif Sarı, 46, has been sentenced to 10 years in prison over use of ByLock, an encrypted mobile app that Turkish government sees as a communication tool among followers of the Gulen group. He has been held in solitary confinement at İzmir Kırıklar F Type Prison since January 2020.

Speaking to the media, Sarı’s wife, Melike, said that he was hospitalized on Tuesday: “The doctor diagnosed him with facial paralysis. … His health is not good. We are very concerned.”

Turkish government accuses Gulenists of masterminding the July 15, 2016 failed coup while the group denies involvement. Interior Minister Suleyman Soylu said at least 510,000 people have been detained over Gulen links since the summer of 2016.
