Presidents Clinton and Carter, Pope John Paul II, Henry Kissinger, the Empire State Building, the Library Tower in Los Angeles and the Sears Tower in Chicago were among the targets of al Qaeda attacks planned by captured al Qaeda terror commander Khalid Sheikh Mohammed, according to a written statement he filed this weekend at a hearing held at the American prison at Guantanamo.
Known as KSM, he also formally admitted responsibility for the 9/ll attacks, the 1993 World Trade Center bombing and the bombing of a nightclub in Bali, Indonesia.
KSM, captured in 2003 in Pakistan, was subjected by the CIA to waterboarding and other "extreme interrogation" techniques, according to current and former CIA officials.
Legal experts say his case will test whether confessions made as the result of such techniques will be admissible under the rules of the special Combatant Tribunals established by the Bush administration.
KSM's confession is a remarkable document, listing most of the known, and a few unknown, terror attacks or plots over the last 10 years.
"I was responsible for the 9/ll operation, from A to Z," the declaration reads.
He also says he was responsible for planning and financing a "second wave" of attacks that targeted the Library Tower in Los Angeles, the Sears Towers in Chicago, the Plaza Bank in Washington State and the Empire State Building in New York.
FBI officials in Chicago had previously denied ABC News reports that the Sears Tower was a possible target.
He says the Sears Tower was to be destroyed by "burning a few fuel or oil tanker trunks beneath it or around it."
KSM also says he was planning attacks on American military vessels in the Straights of Hormuz, Gibraltar and the Port of Singapore, along with a plan to bomb and destroy the Panama Canal.
Also on KSM's plot list: U.S. embassies, Israeli embassies, Israeli passenger jets at the Bangkok Airport, U.S. targets in South Korea, NATO headquarters, U.S. nuclear power plants and "an American oil company owned by the Jewish former Secrreatry of State, Henry Kissinger, on the island of Sumatra, Indonesia."
