Internet users in China were blocked from seeing YouTube.com on Sunday after dozens of videos about protests in Tibet appeared on the popular video website, The Wall Street Journal reported.

According to the WSJ, the Chinese government has not commented on whether it prevented access to YouTube -- said to be part of the communist country's efforts to control what the public saw and heard about protests that erupted Friday in the Tibetan capital against Chinese rule -- but internet users in China who tried to call up YouTube were presented with a black screen.

Just last month, millions of YouTube fans around the globe lost access to the video sharing site after the Pakistani government attempted to block it from its citizens because of concerns over anti-Islamic videos.
