BEIJING  A terrorist group seeking an independent Muslim state in western China has released a video threatening an attack on the Olympic Games here, according to an American organization that tracks terrorist Internet posts.

The video’s opening graphics show a burning Olympic logo and an explosion superimposed over one of the athletic sites, said the monitoring organization, IntelCenter, based in Alexandria, Va.

According to IntelCenter’s description, a man holding an assault rifle, who identifies himself as Abdullah Mansour, says in the Uighur language: “We, members of the Turkestan Islamic Party, have declared war against China. We oppose China’s occupation of our homeland of East Turkestan, which is a part of the Islamic world.”

He warns Muslims not to go to the Games and not to let their children go. “We do not want to see any Muslim brothers and sisters who believe in Allah and his Holy Prophet Muhammad, who believe in the next life and the day of judgment, get hurt by our fire targeted at China,” he says.
