Two suspected terrorists being held at the U.S. naval base in Guantanamo Bay, Cuba will appear before a military tribunal this week.
Preliminary hearings will be held Wednesday in the cases of Canadian-born Omar Ahmed Khadr and Yemeni national Ali Hamza Ahmad al-Bahlul.
Khadr was just 15 when he was captured in Afghanistan for allegedly killing a U.S. serviceman while fighting with al Qaida militants.
Officials say al-Bahlul was commissioned by al Qaida leader Osama bin Laden to produce propaganda video. During a hearing last August, he claimed membership in al Qaida and asked to represent himself.
Critics have argued the hearings should be postponed until the U.S. Supreme Court rules on the constitutionality of the military tribunals in a related case later this year.
