Six detainees at Guantanamo Bay were charged with murder and war crimes for the Sept. 11, 2001 terrorist attacks.
The 169 charges were announced in a Pentagon news conference Monday.
The government will submit the charges against the detainees, who include alleged 9/11 mastermind Khalid Sheik Mohammed, Brig Gen. Thomas Hartman, legal adviser to the military commissions trying the detainees, said at the conference.
The U.S. military will recommend that all six men be tried together before a military tribunal. The government plans to seek the death penalty.
Last week it was revealed that Mohammed was subjected to waterboarding, a type of interrogation technique that some consider torture. It is unclear how that will affect the case.
Some 2,974 people were killed in the 9/11 attacks, as well as 19 hijackers. The hijackers flew two commercial airplanes into the World Trade Center in New York and another into the Pentagon in Washington. Another plane crashed in western Pennsylvania after passengers wrested control from the hijackers.
