Der Spiegel will later report that in a “very brief conversation Osama [tells] his mother that he [will] not be able to call again for a long time, a remark that seem[s] cryptic to the agents listening in at the time, especially when Osama add[s] that ‘great events are about to take place.’” The NSA had been tracking Osama bin Laden’s satellite phone number since 1996, and also tracking the number of his mother, Hamida al-Attas, living in Saudi Arabia, on the off chance he would call her and tell her something important. Bin Laden apparently had called her more than anyone else, but this is his last call to her. Around this time, President Bush is so convinced that the best way to catch bin Laden is through his mother that he is reputed to tell the Emir of Qatar, “We know that he’ll call his mother one day – and then we’ll get him.” Hamida has remained loyal to her son in the wake of 9/11, saying in 2003, “I disapprove of the ambitions the press ascribe to him, but I am satisfied with Osama, and I pray to God that He will guide him along the right path.”
[CNN, 3/12/2002; Der Spiegel (Hamburg), 6/6/2005] Note that this warning is similar to, but apparently different from, another warning phone call bin Laden makes in early September 2001. That call is to Al-Khalifa bin Laden, his stepmother and not his mother, who lives in Syria and not Saudi Arabia (see September 9, 2001).
