WINNIPEG, Manitoba (Reuters) - The youngest prisoner and last Westerner held in the Guantanamo military base, Omar Khadr, was sent to finish his sentence in his native Canada on Saturday, the Canadian government confirmed.

Canadian Public Safety Minister Vic Toews said that Khadr, who was a 15-year-old fighting in Afghanistan when captured in 2002, had been flown to a military base in Trenton, Ontario and transferred to the province's Millhaven prison.
