Afghanistan: 'Newsweek magazine backed away Sunday from a report that U.S. interrogators desecrated copies of the Quran while questioning prisoners at the Guantanamo Bay naval base -- an account blamed for sparking violent riots in Afghanistan and elsewhere. At least 15 people were killed and dozens injured last week when thousands of demonstrators marched in Afghanistan and other parts of the Muslim world, officials and eyewitnesses said.' (CNN)
