WASHINGTON  Six Guantánamo detainees who are accused of central roles in the terror attacks of Sept. 11, 2001, will be shown all the evidence against them and will be afforded the same rights as American soldiers accused of crimes, the Pentagon said Monday as it announced the charges against them.

Military prosecutors will seek the death penalty for the six Guantánamo detainees on charges including conspiracy and murder “in violation of the law of war,” attacking civilians and civilian targets, terrorism and support of terrorism, Brig. Gen. Thomas Hartmann of the Air Force, legal adviser to the Defense Department’s Office of Military Commissions, said at a Pentagon news briefing.

General Hartmann said it would be up to the trial judge how to handle evidence obtained through controversial interrogation techniques like “waterboarding,” or simulated drowning. Critics have said the harsh techniques, which are believed to have been used on several of the defendants, amount to torture.

As expected, the six include Khalid Shaikh Mohammed, the former Qaeda operations chief who has described himself as the mastermind of the Sept. 11 attacks, which killed nearly 3,000 people.
