Sept. 11 Suspects to Be Tried by Military The Defense Department has referred charges including terrorism, hijacking, murder and war crimes against Khalid Sheikh Mohammed and four others accused of planning the Sept. 11, 2001, attacks to a commission for trial by a military judge at Guantánamo Bay, Cuba, the Pentagon said on Wednesday. The five, who will be arraigned within 30 days, could be sentenced to death if convicted. Earlier proceedings against the men were suspended when the Obama administration proposed a civilian trial in New York. Congressional and local opposition stymied the move.
