Pussy Riot members insist they are still part of the punk group Two members of the Russian punk group Pussy Riot, who had been imprisoned for two years, claimed they were still part of the movement during a press conference in Berlin on Monday, after other members disowned them in a letter posted on the group's blog. The letter signed by six members of Pussy Riot lashed out at Nadezhda Tolokonnikova and Maria Alyokhina for taking part in the concert organised by Amnesty International with Madonna in New York on Wednesday.
