“In August 2001, either NSA [National Security Agency] or Britain’s GCHQ [Government Communications Headquarters] intercepted a telephone call from one of bin Laden’s chief lieutenants, Abu Zubaida, to an al Qaeda operative believed to have been in Pakistan. The intercept centered on an operation that was to take place in September. At about the same time, bin Laden telephoned an associate inside Afghanistan and discussed the upcoming operation. Bin Laden reportedly praised the other party to the conversation for his role in planning the operation. For some reason, these intercepts were reportedly never forwarded to intelligence consumers, although this contention is strongly denied by NSA officials.” [The 15th of the month used for date sorting purposes only.]
