Khalid Sheikh Mohammed, al-Qaida's No.3, operational leader, and alleged Sept. 11 mastermind, is seen shortly after his CIA capture during a raid in Pakistan March, 2003. Months later Mohammed acknowledged knowing his one-time protege, Abu Ahmed al-Kuwaiti, but denied he was an al-Qaida figure of any importance. The CIA suspected a lie and reasoned that if they could find al-Kuwaiti, they could find bin Laden. Al-Kuwaiti, who had become one of al-Qaida's most important couriers, eventually and unwittingly led the agency to Osama bin Laden's doorstep in Pakistan. Mohammed and other alleged 9/11 plotters are currently being held at Guantanamo Bay.
