Russian punk band Pussy Riot to appear in court over church gig

18 April 2012 Last updated at 09:54 BST

Three women detained for singing a political punk song in Moscow's main cathedral will ask a court to set them free later this week. If found guilty they face up to seven years in prison.

The actions of the group have sparked a furious debate over the role of the church, which has asked for the women to be treated severely.
