Guantanamo Bay, Cuba (CNN) -- The youngest detainee in the U.S. facility Guantanamo Bay is set to go to trial this week, charged with terrorist acts for al Qaeda and the killing of a U.S. Special Forces soldier.
The Pentagon-appointed lawyer for Canadian citizen Omar Khadr said he didn't know whether Khadr would be in court Monday.
The day will be devoted to dealing with motions, said defense lawyer Lt. Col. Jon Jackson.
The panel of 15 members of the U.S. military that will act as a jury will be seated by the end of the day on Tuesday.
Khadr was captured on the battlefield in Afghanistan in 2002 when he was only 15. He is now 23.
The government said late Sunday it expected the commission trial to begin on schedule, and that it could last as long as four weeks.
Navy Capt. David Iglesias, a former federal prosecutor and also part of the Navy's Judge Advocate General's Corps, said if Khadr is convicted of serious charges, "the government will ask for life" in prison.
When the case begins, the Canadian branch of Amnesty International will be inside the courtroom. CNN
