The Bojinka plot was a large-scale, three-phase terrorist attack planned by Ramzi Yousef and Khalid Sheikh Mohammed for January 1995. They planned to assassinate Pope John Paul II; blow up 11 airliners in flight from Asia to the United States, with the goal of killing approximately 4,000 passengers and shutting down air travel around the world; and crash a plane into the headquarters of the United States Central Intelligence Agency (CIA) in Fairfax County, Virginia.
The September 11 attacks evolved from the original Bojinka plot.
Khalid Sheikh Mohammed, often known by his initials KSM, is a Kuwaiti terrorist and the former Head of Propaganda for al-Qaeda. He is currently held by the United States at the Guantanamo Bay detention camp under terrorism-related charges. He was named as "the principal architect of the 9/11 attacks" in the 2004 9/11 Commission Report.
