The Guardian has published an open letter from Pussy Riot's Nadezhda Tolokonnikova where she talks about beginning a hunger strike today. She said this:

My brigade in the sewing shop works 16 to 17 hours a day. From 7.30am to 12.30am. At best, we get four hours of sleep a night. We have a day off once every month and a half. […] Just recently, a young woman got stabbed in the head with a pair of scissors because she didn't turn in a pair of pants on time. Another tried to cut her own stomach open with a hacksaw. They stopped her.

I will [not eat] until the administration starts obeying the law and stops treating incarcerated women like cattle ejected from the realm of justice for the purpose of stoking the production of the sewing industry; until they start treating us like humans.
