Summer 2001: NSA Intercepts Calls between 9/11 Hijacker Atta and 9/11 Mastermind KSM; Fails to Share This with Other Agencies

Around this time, the NSA intercepts telephone conversations between 9/11 mastermind Khalid Shaikh Mohammed (KSM) and 9/11 hijacker Mohamed Atta, but apparently it does not share the information with any other agencies. The FBI has had a $2 million reward for KSM since 1998 (see January 8, 1998), while Atta is in charge of hijacker operations inside the US. [Knight Ridder, 6/6/2002; Independent, 6/6/2002] The monitored calls between the two of them continue until September 10, one day before the 9/11 attacks (see September 10, 2001). The NSA either fails to translate these messages in a timely fashion or fails to understand the significance of what was translated. [Knight Ridder, 6/6/2002] However, it will later be revealed that an FBI squad built an antenna in the Indian Ocean some time before 9/11 with the specific purpose of listening in on KSM’s phone calls, so they may have learned about these calls to Atta on their own (see Before September 11, 2001).
