Access to YouTube in China was cut on Sunday after footages of the bloody protests in Tibet appeared on the site.

A black screen and an error message could appear when people tried to open the site, with a message saying the web page could not be displayed.

Several video clips showing violent protests in the Tibetan capital, Lhasa, had been posted on YouTube before the access to the site was cut.

Foreign journalists were denied access to Lhasa and foreign tourists were ordered by China to vacate the city.

However, access to Chinese-language video post such as were operational by late Sunday, although a search for Tibet violence couldn't give results.
