Newly Unsealed Documents Reveal More Details Of Prosecutors' Evidence In 9/11 Attacks

Newly unsealed documents give one of the most detailed views yet of the evidence gathered on the accused 9/11 mastermind Khalid Sheikh Mohammed , including how prosecutors allege he and others interacted with the hijackers who carried out the Sept. 11, 2001 attacks.

The summaries of evidence released Thursday include Mohammed's own statements over the years, phone records and other documents alleging coordination between Mohammed and the hijackers, videos included in al-Qaida's planning for the attacks and prosecutors' summaries of government simulations of the flights of the four airliners that day. But few other details were given.

Also to be presented are the photos and death certificates of 2,976 people killed that day at the World Trade Center, the Pentagon and in a Pennsylvania field, where the fourth airliner commandeered by the al-Qaida hijackers smashed into the ground after a revolt by passengers.

The newly revealed framework of military prosecutors' potential case against Mohammed, who prosecutors say conceived of and executed much of al-Qaida's attack, is contained in a plea agreement that the Defense Department is battling in court to roll back.

Mohammed and two co-defendants agreed in the plea deal with military prosecutors to plead guilty in the attack in return for life sentences.
