It shows that the overwhelming majority of Muslims condemned the attacks against the United States on September 11, 2001 and other subsequent terrorist attacks, the authors of the study said in Washington.

"Samuel Harris said in the Washington Times (in 2004): 'It is time we admitted that we are not at war with terrorism. We are at war with Islam'," Dalia Mogadeh, co-author of the book "Who Speaks for Islam" which grew out of the study, told a news conference here.
