The manual includes information on the legal definition of torture and tips on how to tell if Canadians being held as prisoners outside the country's borders have been abused, The Toronto Star reported.

Afghanistan, China, Egypt, Guantanamo Bay, Iran, Israel, Mexico, Saudi Arabia, Syria and the United States are listed under "possible torture/abuse cases."

The Foreign Affairs Department prepared the guide, "Torture Awareness Workshop Reference Materials," because of the case of Omar Khadr -- a Canadian citizen who was arrested as a teenager in Afghanistan, where he had gone with his family, and held in Guantanamo.

The United States says he has been treated well there, but Khadr claims extreme abuse, including being used as "a human mop" and being chained up for hours.
