A member of a popular folk music group that is banned in Turkey has died on the 288th day of a hunger strike protesting the imprisonment of band members.

Helin Bolek died Friday at her İstanbul home where she had been staging the hunger strike to force the Turkish government to relese all the members of the Group Yorum, a band known for its protest songs.

Grup Yorum has been banned from performing since 2016, and some band members have been jailed.

The government accuses Group Yorum of links to the Revolutionary People’s Liberation Party-Front (DHKP/C).
