Amnesty International has said its Turkish branch chairman will remain in jail after a court overturned an earlier decision for his release on bail.

The human rights group said Taner Kilic was ordered arrested again on Thursday after a prosecutor appealed another court’s decision that he should be freed from jail pending a verdict in his trial on terror-related charges.

Kilic is on trial with 10 other activists detained in a police raid in July while attending a workshop on digital security. They were charged with belonging to and abetting terror organisations. All of them except Kilic have been released on bail.

Amnesty called the decision a “travesty of justice of spectacular proportions”.

The group said the next hearing in his trial has been set for June 21.
