A Turkish lawyer who was on hunger strike for 238 days following her conviction last year for membership in a terrorist organization died on Thursday in an Istanbul hospital, according to her law firm, Reuters reports.

International lawyers rights groups said that Timtik, sentenced to more than 13 years in prison, and colleague Aytac Unsal began fasting in April “to strengthen their demand for fair trials and the administration of justice in Turkey.”

An appeal to the March 2019 verdict was rejected in October and a further appeal before Turkey’s Supreme Court is pending, the statement said.
