Eleven human rights activists, including two local heads of Amnesty International, who were charged with links to terror groups will go on trial in Turkey on October 25.
The state-run Anadolu Agency said a court on Tuesday approved the charges of "membership in a terror organisation" and "aiding an armed terror group" against the activists.
Ten activists including Amnesty's Turkey director Idil Eser, German national Peter Steudtner and Swede Ali Gharavi were arrested during a workshop on digital security at a hotel near Istanbul in July.
They are accused of aiding Kurdish and left-wing militants as well as the movement led by US-based cleric Fethullah Gulen, blamed for last year's failed coup attempt.
Amnesty's Turkey chairman Taner Kilic, imprisoned in June, will be tried alongside the 10.
