Khalid Sheikh Mohammed, suspected mastermind of the Sept. 11, 2001, attacks, confessed to that attack and a string of others during a military hearing at Guantanamo Bay, Cuba, according to a transcript released by the Pentagon.
"I was responsible for the 9/11 operation from A to Z," Mohammed said in a statement read during the session, which was held last Saturday.
Mohammed claimed responsibility for planning, financing and training others for attacks ranging from the 1993 truck bombing of the World Trade Center to the attempt by would-be shoe bomber Richard Reid to blow up a trans-Atlantic flight with explosives hidden in his shoes. He also claimed he was tortured by the CIA after his capture in 2003.
In all, Mohammed said he was responsible for planning 28 attacks, including many that never were executed. The comments were included in a 26-page transcript released by the Pentagon, which blacked out some of his remarks.
