A court ordered the YouTube Web site blocked throughout Turkey because of a video deemed insulting to Mustafa Kemal Ataturk, the founder of modern Turkey. The ban followed a week of what the news media termed a “virtual war” of videos between Greeks and Turks on YouTube. The largest Internet provider, Turk Telecom, complied with the ban and cut off access to the site. Insulting Ataturk is a criminal offense in Turkey.
