A Moscow court has ruled that the video of punk band Pussy Riot's performance in Russia's main cathedral is extremist and ordered it to be removed from the web.

The band was protesting President Vladimir Putin's impending third term as the country's president.

Three members of the band were found guilty of hooliganism motivated by religious hatred earlier this year. Two of them received two-year sentences while the third was given a suspended sentence. Putin's critics described the Pussy Riot trial as a political vendetta.

The Moscow court on Thursday banned the video of their February performance and said it should be removed from all websites.
