FBI warn al-Qaida may launch a 'spectacular attack' on the US

Washington

An FBI law enforcement bulletin circulated Thursday to officials nationwide contains no information about the timing, location or method of a possible attack. Even so, the warning is unusual because of its dire language.

"Sources suggest al-Qaida may favour spectacular attacks that meet several criteria: High symbolic value, mass casualties, severe damage to the US economy and maximum psychological trauma," says the alert, which was posted on the FBI's Web site early Friday after its existence was reported by The New York Times and The Associated Press.
