An Uşak court on Tuesdayruled for continuation of imprisonment of  Ali Ünal, a theologian and a former columnist for the now-closed Zaman daily, several media outlets reported.

Ünal has been behind bars for almost 18 months. The second hearing of Ünal’s trial was held at the Uşak 2nd High Criminal Court on Tuesday. Ünal, who is incarcerated in a high-security prison in İzmir province, is accused of “attempting to overthrow the constitutional order,” “establishing and managing an armed terror organization” and “being a member of a terror organization.”

Detained in Usak’s Esme district on Aug 11, 2016, Unal was put under pretrial detention 5 days later. Under arrest since then, Unal said during his first hearing: “I am 63 years old. I wrote more than 90 books, 30 of which were translated into different languages. I don’t know why I am in jail.”

Zaman was earlier closed due to its links to the Gulen group, which the government accuses of masterminding the July 15, 2016 coup attempt and considers a terrorist organization.

The movement denies coup and terror charges, asking the government about concrete evidence to back up its accusations.
