In the wake of the arrest of Ahmed Ressam (see December 14, 1999), FBI investigators work frantically to uncover more millennium plots before the end of the year. US authorities also make a number of arrests. A telephone number found in Ressam’s pocket leads to Abdel Ghani Meskini, an Algerian living in New York City who had gone to Seattle to meet Ressam. Meskini is monitored and arrested in New York on December 30.
One of Ressam’s credit cards leads to the arrest of Mokhtar Haouari, an Algerian living in Montreal, Canada. Meskini later cooperates with US investigators and is never charged, while Haouari will be sentenced to 24 years in prison. [Time, 2/7/2000; CNN, 1/16/2002; Wright, 2006, pp. 298]

Investigators believe that Mohamedou Ould Slahi, an al-Qaeda operative whose cousin is a top al-Qaeda leader, went to Canada to give the go-ahead for Ressam’s attack. Slahi is arrested several times overseas, but never charged (see January-April 2000). [CNN, 3/6/2002]
Khalid Deek, a US citizen, is arrested around this time for masterminding another al-Qaeda millennnium plot (see December 11, 1999). But counterterrorism expert Rita Katz will later say Deek was a suspected mastermind of Ressam’s Los Angeles airport plot, too. [Orange County Register, 9/12/2005] Deek’s name and phone number is found in Ressam’s telephone book. Ressam knew Deek from bin Laden training camps in Afghanistan. Both of them, like most of Ressam’s group, have links to the GIA, an Algerian militant group associated with al-Qaeda. [Newsweek (International), 3/13/2000]
Others escape the US after hearing media reports of Ressam’s arrest. However, enough people are caught to stop additional millennium attacks. Counterterrorism “tsar” Richard Clarke later says, “I think a lot of the FBI leadership for the first time realized that… there probably were al-Qaeda people in the United States. They realized that only after they looked at the results of the investigation of the millennium bombing plot.” [PBS Frontline, 10/3/2002] Yet Clinton’s National Security Adviser Sandy Berger later claims that the FBI will still repeatedly assure the Clinton White House until Clinton leaves office that al-Qaeda lacks the ability to launch a domestic strike (see 2000).
