Who are Khalid Sheikh Mohammed and the other accused terrorists?
Khalid Sheikh Mohammed and four others are to stand trial in New York. Here's the evidence federal prosecutors will use against them.
All five men were called before combat status review tribunals two years ago at the Guantánamo detention camp.
Transcripts of the tribunals offer a rough preview of the kind of case that may emerge against each of the five terror suspects.
What follows is a summary of the allegations and known evidence for each of the five prospective defendants:
Khalid Sheikh Mohammed
The self-described mastermind of the 9/11 attacks, offered a complete confession in a combat status review tribunal conducted at Guantánamo Bay in 2007. It is unclear whether this confession will be admitted as evidence in his trial. It may offer a preview of Mr. Mohammed's trial strategy – to admit involvement in a wide range of terror attacks and die a martyr after being convicted and sentenced to death.
"I was responsible for the 9/11 operation, from A to Z," he told the military tribunal in March 2007.
He admitted to swearing an oath of allegiance to Osama Bin Laden to conduct jihad and to serving Bin Laden as operational director for the "organizing, planning, follow-up, and execution of the 9/11 operation."
Mohammed was subject to some of the harshest interrogation tactics used by US officials. He was reportedly waterboarded 183 times. In his 2007 statement, he complained bitterly about being tortured by the CIA, but it didn't seem to temper his apparent desire to confess.
