GUANT脕NAMO BAY, Cuba 鈥 After expressing their desire to plead guilty at a Guant谩namo military commission hearing earlier today, Khalid Sheikh Mohammed and two other detainees charged with crimes related to the 9/11 attacks said they would postpone entering pleas until the competency of two additional co-defendants is determined. Outstanding questions remain about whether the death penalty can be imposed if the defendants plead guilty.
