Khalid Sheikh Mohammed portrayed himself as Al Qaeda's most ambitious operational planner in a confession to a U.S. military tribunal that said he planned and supported 31 terrorist attacks, topped by Sept. 11, that killed thousands of innocent victims since the early 1990s.
The gruesome attacks range from the suicide hijackings of Sept. 11, 2001 — which killed nearly 3,000 — to a 2002 shooting on an island off Kuwait that killed a U.S. Marine, according to an account released by the Pentagon.
Many plots, including a previously undisclosed plan to kill several former U.S. presidents, were never carried out or were foiled by international counterterror authorities.
"I was responsible for the 9/11 operation from A to Z," Mohammed said in a statement read Saturday during a Combatant Status Review Tribunal at the U.S. detention facility at Guantanamo Bay, Cuba. Mohammed's confession was read by a member of the U.S. military who is serving as his personal representative.

The Pentagon released a 26-page transcript of the closed-door proceedings on Wednesday night. Some material was omitted, and it wasn't possible to immediately confirm details. The document refers to locations for which the United States and other nations have issued terrorism warnings based on what they deemed credible threats from 1993 to the present.
Mohammed, known as KSM among government officials, was last seen haggard after his capture in March 2003, when he was photographed in a dingy white T-shirt with an over-stretched neck. He disappeared for more than three years into a secret detention system run by the CIA.
In his first public statements since his capture, his radical ideology and self-confidence came through. He expressed regret for taking the lives of children and said Islam doesn't give a "green light" to killing.
Yet he finds room for exceptions. "The language of the war is victims," he said.
He also said some people "consider George Washington as hero. Muslims many of them are considering Usama bin Laden. He is doing same thing. He is just fighting. He needs his independence."
In laying out his role in 31 attacks, his words drew Al Qaeda closer to plots of the early 1990s than the group has previously been linked, including the 1993 World Trade Center truck bombing in which six people died.
Six people with links to global terror networks were convicted in federal court and sentenced to life in prison for that attack.
Mohammed made clear that al-Qaida wanted to down a second trans-Atlantic aircraft during would-be shoe bomber Richard Reid's operation.
And he confessed to the beheading of Wall Street Journal reporter Daniel Pearl in a section of the statement that was excised from the public document, The Associated Press has learned. Pearl was abducted in January 2002 in Pakistan while researching a story on Islamic militancy. Mohammed has long been a suspect in the slaying, which was captured on video.
President Bush announced that Mohammed and 13 other alleged terror operatives had been moved from secret CIA prisons to the U.S. Naval Base at Guantanamo Bay last year. They are considered the 14 most significant captures since 9/11.
The military began the hearings last Friday to determine whether the 14 should be declared "enemy combatants" who can be held indefinitely and prosecuted by military tribunals.
If the 14 are declared enemy combatants, as expected, the military would then draft and file charges against them. The detainees would be tried under the new military commissions law signed by Bush in October.
The military barred reporters or other independent observers from the sessions for the 14 operatives and is limiting the information it provides about them, arguing that it wants to prevent the disclosure of sensitive information.
Legal experts have criticized the U.S. decision, and The Associated Press filed a letter of protest, arguing that it would be "an unconstitutional mistake to close the proceedings in their entirety."
The transcripts refer to a claim by Mohammed that he was tortured by the CIA, although he said he was not under duress at Guantanamo when he confessed to his role in the attacks. The CIA has said its interrogation practices are legal, and it does not use torture.
Kenneth Roth, executive director of Human Rights Watch, questioned the legality of the closed-door sessions and whether the confession was actually the result of torture.
"We won't know that unless there is an independent hearing," he said. "We need to know if this purported confession would be enough to convict him at a fair trial or would it have to be suppressed as the fruit of torture?"
In listing the 28 attacks he planned and another three he supported, Mohammed said he tried to kill international leaders including Pope John Paul II, President Clinton and Pakistani President Pervez Musharraf.
He said he planned the 2002 bombing of a Kenya beach resort frequented by Israelis and the failed missile attack on an Israeli passenger jet after it took off from Mombasa, Kenya.
He also said he was responsible for the bombing of a nightclub in Bali, Indonesia. In 2002, 202 were killed when two nightclubs there were bombed.
Other plots he said he was responsible for included planned attacks against the Sears Tower in Chicago, the Empire State Building and New York Stock Exchange in New York City, the Panama Canal, and Big Ben and Heathrow Airport in London — none of which happened.
The Pentagon also released transcripts of the hearings of Abu Faraj al-Libi and Ramzi Binalshibh. Both refused to attended the hearings, although al-Libi submitted a statement claiming that the hearings are unfair and that he will not attend unless it is corrected.
"The detainee is in a lose-lose situation," he said.
Al-Libi, whose name means he is a Libyan, reportedly masterminded two bombings 11 days apart in Pakistan in December 2003 that targeted Musharraf for his support of the U.S.-led war on terror.
Binalshibh, a Yemeni, is suspected of helping Mohammed with the Sept. 11 attack plan on New York City and Washington and is also linked to a foiled plot to crash aircraft into London's Heathrow Airport. His hearing was conducted in his absence.
