Fresh concerns have been raised about one of the jailed members of Russian punk rock band Pussy Riot.

The husband of Nadezhda Tolokonnikova has told Al Jazeera that he has not heard from his wife since she was moved to a new prison.

She and a bandmate were jailed last year for a protest against President Vladimir Putin inside a Moscow cathedral.
