US files new charges against accused 9/11 planners

US files new charges against accused 9/11 planners. U.S. military prosecutors have filed new charges against the self-described mastermind of the September 11 attacks in 2001, Khalid Sheikh Mohammed, and four alleged co-conspirators held at the Guantanamo detention camp.

The conspiracy and mass murder charges were expected to be announced later on Tuesday, according to sources involved in the war crimes tribunals at the U.S. naval base in Guantanamo Bay, Cuba.

During President George W. Bush's administration, all five defendants had been charged in the tribunals with plotting the attacks, which killed nearly 3,000 people in the United States.
