Tverskoi court's ruling follows a similar local decision taken last week by a court in Grozny, the provincial capital of Russia's Muslim-dominated province of Chechnya.

In Moscow, Justice Ministry spokeswoman Marina Gridneva said the film was deemed extremist because it could incite ethnic and religious hatred.

Russia's communications minister had warned that authorities would bar access to YouTube if its owner, Google Inc., failed to abide by a court order to block access in this nation to the U.S.-produced film, which mocks Muslims and the Prophet Muhammad.

Google in Russia has said it could restrict access to the video, if it received a court order outlawing it, but the company declined to discuss that issue with The Associated Press on Monday evening.
