Six men are being detained in a Canadian prison on "security certificates" - secret documents that not even their lawyers can see. No charges have been laid against them. They are currently on a hunger strike. A website has been set up to offer detailed news on the situation here.
To quote the text on the website:
"In reverse chronological order, below are statements, letters, and background information on the life-and-death situation at Canada's Guantanamo Bay. While six former foreign ministers for Canada have rightfully spoken up against the brutality of the Guantanamo Bay facility in Cuba, they remain shamefully silent on what is happening in their own back yard."
