GUANTANAMO BAY NAVAL BASE, Cuba (AP) — A U.S. military judge is considering broad security rules for the war crimes tribunal of five Guantanamo prisoners charged in the Sept. 11 attacks, including measures to prevent the accused from publicly revealing what happened to them in the CIA's secret network of overseas prisons.

Prosecutors have asked the judge at a pretrial hearing starting Monday to approve what is known as a protective order that is intended to prevent the release of classified information during the eventual trial of Khalid Sheikh Mohammed, who has portrayed himself as the mastermind of the terror attacks, and four co-defendants.
