MOSCOW – An imprisoned member of the punk band Pussy Riot ended her nine-day hunger strike Tuesday but her husband said she has vowed to restart it if she is not moved to another prison.

Pyotr Verzilov said his wife, Nadezhda Tolokonnikova, was in stable condition after a hunger strike to protest working conditions in the women’s prison where she is serving a two-year sentence. She and two other members of the group were convicted of hooliganism for performing a provocative “punk prayer” in Moscow’s main Orthodox cathedral in 2012 denouncing Vladimir Putin, who was returning to the presidency.

The Federal Penitentiary Service confirmed that Tolokonnikova ended the hunger strike Tuesday, two days after she was transferred to a prison hospital. Her lawyer said her client’s deteriorating health had been the main factor in calling off the hunger strike.
