December 1991-May 1992: Bin Laden-Linked Bomber Ramzi Yousef Trains Philippine Militants

Ramzi Yousef, the future bomber of the WTC in 1993, stays in the Philippines and trains militants there in bomb-making. According to Philippine intelligence documents, Yousef had developed expertise in bomb-making and worked at a training camp at Khost, Afghanistan, teaching bomb-making for militants connected to bin Laden. But bin Laden dispatches him to the Philippines, where he trains about 20 militants belonging to the Abu Sayyaf group. Abu Sayyaf is heavily penetrated by Philippine undercover operatives at this time, especially Edwin Angeles, an operative who is the second in command of the group. Angeles will later recall that Yousef is introduced to him at this time as an “emissary from bin Laden.” [Strategic Studies Institute of the US Army War College, 9/1/2005 ] Angeles also claims Yousef decided to use the Philippines as a “launching pad” for terrorist acts around the world. [New York Times, 9/6/1996] One of Abu Sayyaf’s top leaders will later recall that Yousef also brings a significant amount of money to help fund the group. [Philippine Daily Inquirer, 1/22/2007; CNN, 1/31/2007] A flow chart of Yousef’s associates prepared in early 1995 by Angeles’ Philippines handler Rodolfo Mendoza shows a box connected to Abu Sayyaf labeled “20 trainees/recruits.” So presumably the Philippine government is aware of this information by then, but it is not known when they warned the US about it (see Spring 1995). Yousef will also later admit to planning the 1993 WTC bombing at an Abu Sayyaf base, which most likely takes place at this time (see Early 1992). The ties between Yousef and Abu Sayyaf will grow stronger, culminating in the 1995 Bojinka plot (see January 6, 1995), an early version of the 9/11 plot.
