The Al-Qaeda network has threatened Canada with terrorist attacks if Ottawa fails to withdraw its troops deployed in Afghanistan, a media report said.
The threat was issued by a member of the Al-Qaeda information and strategy committee, Hossam Abdul Raouf, in a document written in July, the National Post reported.
Raouf wrote that the Canadians "will either be forced to withdraw their forces or face an operation similar to New York, Madrid, London."
The document was obtained and translated by a US non-profit organisation, the SITE Institute, which monitors the Internet for terrorist threats, the paper said on Saturday.
"Despite the strong increasing opposition to spread its forces in the fire of south Afghanistan, it seems that they (Canadians) will not learn the lesson easily," Raouf wrote.
The document condemns Canadian Prime Minister Stephen Harper for keeping troops in Afghanistan and refers to Canada's support for a "crusade" against Al-Qaeda.
Close to 2,500 Canadian soldiers are deployed in the Kandahar region in southern Afghanistan, fighting Taliban insurgents.
