ANKARA, Turkey (AP) — A human rights lawyer in Turkey has died of a hunger strike she launched in prison to demand a fair trial for herself and colleagues, an attorney’s group said.

Ebru Timtik, 42, died in a hospital in Istanbul late Thursday, the Progressive Lawyers’ Association said. 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.

Opposition parties have long questioned the impartiality and independence of Turkey's courts under President Recep Tayyip Erdogan's rule, while lawyers' groups reported several flaws during the trial. They included the removal of judges who had initially ordered the lawyers' release from pretrial detention and the use of anonymous witnesses who testified against them.

European Commission spokesman Peter Stano said the EU is “deeply saddened” by Timtik's death.

“Ebru Timtik's hunger strike for a fair trial and its tragic outcome painfully illustrate the urgent need for the Turkish authorities to credibly address the human rights situation in the country and the serious shortcomings observed in the Turkish judiciary,” Stano said.

“A strong and independent legal profession, along with an independent judiciary is a core principle of a fair justice system,” he said.

Hunger strikers in Turkey traditionally refuse food but consume liquids and take vitamins that prolong their protests.

Timtik’s death comes months after two members of a left-wing popular folk group that is banned in Turkey also died of a hunger strike. They had also been accused of links to the DHKP/C.
