Pakistan's government has banned access to the video-sharing Web site YouTube because of anti-Islamic movies that users have posted on the site, an official said. The Pakistan Telecommunication Authority told the country's 70 Internet service providers on Friday that the popular Web site would be blocked until further notice. The authority did not specify what the offensive material was, but a PTA official said Sunday that the ban concerned a movie trailer for an upcoming film by Dutch lawmaker Geert Wilders, who has said he plans to release an anti-Quran movie portraying the religion as fascist and prone to inciting violence against women and homosexuals. The PTA official, who asked not to be identified because he was not an official spokesman, said the Pakistan Telecommunication Authority also blocks Web sites that show controversial drawings of the Prophet Muhammad. The drawings were originally printed in European newspapers in 2006 and were reprinted by some papers last week.
