1991: KSM Proves Worth to Al-Qaeda while Building Network in Philippines

Counterterrorism expert Rohan Gunaratna will later write that Khalid Shaikh Mohammed (KSM) first “earned his spurs” in al-Qaeda by serving as one of Osama bin Laden’s first bodyguards. Then, in 1991, bin Laden sends KSM to the Philippines where he trains members of the militant groups Abu Sayyaf and the Moro Islamic Liberation Front (MILF) in bomb making and assassination. He works with bin Laden’s brother-in-law Mohammed Jamal Khalifa to establish an operational base there and also in Malaysia. Presumably he also works with his nephew Ramzi Yousef, who trains Abu Sayyaf militants the same year (see December 1991-May 1992). Gunaratna says that “After proving himself an outstanding organizer, [KSM] was given substantial operational authority and autonomy by bin Laden.” However, KSM’s work with the Abu Sayyaf and MILF is soon discovered and he “has been on the run since 1991.” KSM will return with Yousef to the Philippines in 1994 to exploit the network they built and develop the Bojinka plot (see January 6, 1995).
