The FBI has received a "plausible but unsubstantiated" report that al Qaeda terrorists discussed in late September blowing up part of the New York subway system, according to an internal FBI memo dated Tuesday published by AP. “These discussions reportedly involved the use of suicide bombers or explosives placed on subway/passenger rail systems," says the FBI assessment. "We have no specific details to confirm that this plot has developed beyond aspirational planning, but we are issuing this warning out of concern that such an attack could possibly be conducted during the forthcoming holiday season.” Intelligence and homeland security officials are working with local authorities and " will continue to investigate every possible lead," the memo says.
