US intelligence obtains information that al-Qaeda is planning to infiltrate the US from Canada and carry out an operation using high explosives. The report does not say exactly where, when, or how an attack might occur. Two months later, the information is shared with the FBI, the INS, the US Customs Service, and the State Department, and it will be shared with President Bush in August. [US Congress, 9/18/2002; Washington Post, 9/19/2002] This information could come from captured al-Qaeda operative Ahmed Ressam, who warns around this month that al-Qaeda leader Abu Zubaida has been seeking Canadian passports as part of a plot to attack the US, possibly by planting explosives in several US cities (see May 30, 2001 and May 2001).
