March 2001: Source Claims Al-Qaeda to Attack Inside the US in April

An intelligence source claims that a group of al-Qaeda operatives is planning to conduct an unspecified attack inside the US in April. One of the operatives allegedly resides in the US. There are also reports of planned attacks in California and New York State for the same month, though whether this is reference to the same plot is unclear. [US Congress, 7/24/2003 ]
