GUANTANAMO BAY NAVAL BASE, Cuba (AP) - The military tribunal for the Sept. 11 terrorism case at Guantanamo is back in session but without three of the five defendants.

Two of the men apparently have taken advantage of the judge's ruling that they have a right to be absent from a weeklong pretrial hearing at the U.S. base in Cuba.

Among those who chose to sit out Tuesday's session is the main defendant, Khalid Sheikh Mohammed. He has previously portrayed himself as the mastermind of the worst terrorist attack on U.S. soil. All five face the death penalty if convicted of planning and aiding the Sept. 11 attacks at their eventual trial, likely more than a year away.
