YouTube has begun restricting access to videos of the offensive film against Islam in the world's most populous Muslim nation, a government official said Sunday.

"Google, which is YouTube's parent company, emailed us on Thursday evening to say it had blocked Indonesia's access to 16 URLs related to the "Innocence of Muslims" videos on the site," Communications and Information Ministry spokesperson Gatot Dewa Broto told Agence France Presse.

Extracts of the film were still available on the video-sharing website on Sunday, but Broto said Google was "making special effort" to prevent the film from being watched in Indonesia.

"We understand that it takes time for Google to block everything as people continue to upload those sensitive videos. We appreciate Google's cooperation," he said.

Broto said the government also wrote to Blackberry maker Research In Motion on Friday to filter the videos on its smartphones.

Indonesia is the Canada-based company's biggest market outside North America, with subscriptions expected to almost double to 9.7 million by 2015.

"We could access the videos on Blackberry too so we wrote to RIM to ask that it filter them, and RIM has been very co-operative," he added.

Besides Indonesia, Google has denied access to the video in Libya, Egypt and India.

In cities across the Muslim world protesters have vented their fury at the American offensive film by targeting symbols of US influence ranging from embassies and fast food chains.

Hundreds of Indonesians staged rallies against the United States on Friday and Saturday over the film, which insults the Prophet Mohammad (pbuh).
