Another aspect of the story below. From CNN, :
WASHINGTON (CNN) — Intelligence found in Pakistan suggests that suspected al Qaeda operatives in that country contacted an individual or individuals in the United States in the past few months, according to two senior U.S. government sources.
The officials would not characterize the nature of the communication.
But the sources said other information from Pakistan has prompted investigations in the United States to uncover whether there are any individuals or terrorist cells plotting an attack on U.S. soil.
In addition, two senior Pakistani intelligence sources told CNN that there is evidence at least six individuals in the United States were contacted by Muhammad Naeem Noor Khan, an alleged al Qaeda operative who was recently taken into custody in Pakistan. U.S. officials have not confirmed that information.
White House press secretary Scott McClellan told reporters Aboard Air Force One that two intelligence streams “came to light more fully” last Friday. The first dealt with Khan and the other dealt with an undisclosed threat.
“I can’t go further into it because it could compromise some ongoing operations at this point,” McClellan said.
He noted, “When you connect all these streams of intelligence, it paints an alarming picture.”
