INTERNET — Fans mourn the loss of Nadia Tolokonnikova, feminist singer for the anti-Putin punk band Pussy Riot. Tolokonnikova was shot dead in Moscow, Tuesday, by unknown assailants as mourners gathered at Boris Nemtsov’s funeral.

Tolokonnikova’s death marks the second assassination of a famous Putin critic, just one week after Boris Nemtsov was assassinated.

Pussy Riot previously faced street violence from police and thugs during a paint attack in Moscow’s McDonald’s and during the filming of a video at the Sochi winter olympics. Tolokonnikova was imprisoned in Siberia for blasphemy after filming an anti-Putin music video at Moscow cathedral.

Tolokonnikova was also affiliated with Voina, an activist performance art ensemble which staged a famous anti-Medvedev public orgy at a Moscow biology museum. Tolokonnikova also recently appeared on the Netflix original series House of Cards.

Putin continues to enjoy nearly 90% approval ratings in Russia as he concentrates military forces in Crimea.
