In a September 29, 2006, speech, Bush stated: "Once captured, Abu Zubaydah, Ramzi bin al-Shibh, and Khalid Sheikh Mohammed were taken into custody of the Central Intelligence Agency. The questioning of these and other suspected terrorists provided information that helped us protect the American people. They helped us break up a cell of Southeast Asian terrorist operatives that had been groomed for attacks inside the United States. They helped us disrupt an al Qaeda operation to develop anthrax for terrorist attacks. They helped us stop a planned strike on a U.S. Marine camp in Djibouti, and to prevent a planned attack on the U.S. Consulate in Karachi, and to foil a plot to hijack passenger planes and to fly them into Heathrow Airport and London's Canary Wharf."
