TORONTO (AP) — Canadian Prime Minister Justin Trudeau is defending his government's apology and multimillion-dollar payment to a former Guantanamo Bay prisoner who pleaded guilty to killing a U.S. soldier in Afghanistan.

The deal between the government and Omar Khadr's lawyers is based on a 2010 Supreme Court of Canada ruling that Canadian officials violated his rights at Guantanamo.

Trudeau said Saturday at the G20 leaders' summit in Germany that when the government violates any Canadian's constitutional rights, everyone ends up paying for it.

Details of the settlement are confidential, but an official familiar with the deal has said it was for 10.5 million Canadian dollars ($8 million).
