A human rights lawyer on hunger strike in a Turkish prison to demand a fair trial for herself and colleagues has died, an attorney’s group said.

Ebru Timtik, 42, died in an Istanbul hospital. She had been fasting for 238 days.

The lawyer and 17 of her colleagues were accused of links to the outlawed Revolutionary People’s Liberation Party-Front, or DHKP/C, a militant group designated a terrorist organization by Turkey, the United States and the European Union. She was convicted in March 2019 and sentenced to 13 years and six months in prison. Her case was under review by an appeals court.

Timtik started the hunger strike in February to protest alleged unfair proceedings during the trial, along with another colleague, Aytac Unsal, who is reported to be in a critical condition.
