For a second Memorial Day in a row (see May 20-24, 2002), the National Alert Level is raised to orange following warnings that “al-Qaeda has entered an operational period worldwide.” Authorities say that recent attacks abroad have raised concerns about an impending attack on the US. The Department of Homeland Security issued this fourth orange alert due to what it calls “the heightened vulnerability associated with the Memorial Day holiday.” However, Homeland Security Secretary Tom Ridge says there is no “credible, specific information” about targets or method of attack.” He does state that “weapons of mass destruction, including those containing chemical, biological or radiological agents or materials, cannot be discounted.” [CNN, 5/20/2003] But federal law enforcement sources say the credibility of the threat is doubtful.
