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.
