June 2001: US Intelligence Warns of Spectacular Attacks by Al-Qaeda Associates

US intelligence issues a terrorist threat advisory, warning US government agencies that there is a high probability of an imminent attack against US interests: “Sunni extremists associated with al-Qaeda are most likely to attempt spectacular attacks resulting in numerous casualties.” The advisory mentions the Arabian Peninsula, Israel, and Italy as possible targets for an attack. Afterwards, intelligence information provided to senior US leaders continues to indicate that al-Qaeda expects near-term attacks to have dramatic consequences on governments or cause major casualties.
