CALGARY — The Canadian Bar Association is calling for a Canadian detainee held at a U.S. military prison to be immediately released and turned over to Canada.

The Bar Association is urging Prime Minister Stephen Harper to call on the U.S. government to turn 20-year-old Omar Khadr over to Canadian law enforcement officials to be dealt with under Canadian law.

In a letter to Harper, CBA President J. Parker MacCarthy warns that continuing to hold Khadr in Guantanamo Bay is an affront to the rule of law.

Khadr is accused of tossing a grenade that killed a U.S. soldier and injured another in Afghanistan in 2002, when he was 15-years-old.

The CBA says notes that Canada is the only Western country with a citizen still detained at Guantanamo.

Both Australia and the United Kingdom have repatriated their detained citizens.
