Russian computer hackers today attacked the website of the Moscow court that tried and convicted three members of the Pussy Riot punk band last week, RIA Novosti reports.

The Associated Press says the Russian offshoot of the loose-knit movement known as Anonymous first tweeted news that the website of Khamovniki District Court was down.

The hackers posted a message calling for the release of the three members of the punk band who were sentenced to two years in prison on charges of "hooliganism" for mounting a protest at Moscow's largest cathedral in February.

The protest included a profanity-laced song criticizing the Russian Orthodox church and Russian leader Vladimir Putin.

The hackers also posted a music video clip of what RIA Novosti calls "homosexual content" by a Bulgarian pop-folk singer.

In addition, the AP reports, search engines' cached pages show that the hackers posted Pussy Riot's latest song ridiculing Putin.

A press spokesperson for Moscow's Khamovnichesky Court tells the Russian news agency that the website was still down at mid-morning.
