A Turkish court ruled to keep renowned Turkish philanthropist and rights advocate Osman Kavala in prison at his latest court hearing, state-run Anadolu news agency reported.

Kavala is accused of orchestrating the Gezi Park mass protests in the summer of 2013 in a trial described as absurd by rights groups.

Prosecutors claim the Gezi protests were organized from outside the country to “bring Turkey to its knees.”

Kavala has been in jail since November 2017 and has become a symbol of what activists say is the deliberate targeting of civil society.

He was among tens of thousands of people rounded up after an attempted coup in July 2016.

A respected figure in intellectual circles, Kavala is the chairman of the Anatolian Culture Foundation, which seeks to bridge ethnic and regional divides through art, including with neighboring Armenia, with which Turkey has no diplomatic ties.
