Russian Punk stars Pussy Riot are set for another six months behind bars after their protest against Vladmir Putin earlier this year.

The three female musicians will remain in custody in until 12 Janury, 2013, a court has decided. The girls were remanded on hooliganism chargesin February, 2012 for a guerilla concert staged in Moscow's Christ the Saviour Cathedral. They were originally arrested two weeks after the impromptu gig, when a video of the show appeared on YouTube.

Band member Nadezhda Tolokonnikova previously staged a hunger strike in protest against the limited amount of time given to prepare for her court case.

Their defence plea was rejected on the first day of their trial, and Judge Victor Danilkin ordered their stay behind bars be extended to ten months.
