Dale Watson, head of the FBI’s counterterrorism program, sends a memo to FBI Director Louis Freeh warning that Islamic radicals are planning a “terrorist operation.” The memo states that “Sunni extremists with links to Ibn al Kahhatb, an extremist leader in Chechnya, and to Osama bin Laden [have been involved in] serious operational planning… since late 2000, with an intended culmination in late spring 2001.” Watson says the planning was sparked by the renewal of the Palestinian Intifada in September 2000. “[A]ll the players are heavily intertwined,” the memo notes. Additionally, the memo says that “[m]ultiple sources also suggest that [bin Laden’s] organization is planning a terrorist attack against US interests.” The memo is also sent to other FBI officials, such as International Terrorism Operations Section (ITOS) chief Michael Rolince, who will later be involved in the case of Zacarias Moussaoui (see Late August 2001 and (August 30-September 10, 2001)) [Federal Bureau of Investigation, 4/2001 ] Based on this report, ITOS sends an e-mail (see April 13, 2001) to all field offices, asking agents to help identify information pertaining to the “current operational activities relating to Sunni extremism.” The e-mail does not mention Ibn Khattab. [Associated Press, 3/21/2006] These plans may be for the 9/11 attacks—at least some of the alleged hijackers are linked to bin Laden (see January 5-8, 2000), and Zacarias Moussaoui is linked to Ibn Khattab (see Late 1999-Late 2000). Some of the hijackers fought in Chechnya and therefore might also be linked to Ibn Khattab (see 1996-December 2000). Officials at FBI headquarters will later refuse a search warrant for Zacarias Moussaoui’s belongings saying they believe Ibn Khattab is not closely connected to Osama bin Laden and is not hostile to the US (see August 22, 2001 and August 23-27, 2001).
