Newsweek is reporting that two members of Pussy Riot have gone missing:
Two members of Pussy Riot, the all-female Russian punk rock band from Moscow known for their provocative protest lyrics and colorful balaclavas, disappeared on Tuesday while traveling from the Crimean Peninsula to Moscow. […] The women were allegedly in Crimea to protest the detention of filmmaker Oleg Sentsov, who is serving a 20-year sentence on terrorism charges that many say are politically motivated.
Update: They have been found.
