International plot? Not clear

From NBC's Pete Williams and Domenico Montanaro
The car left in Times Square Saturday night is yielding several promising clues, officials say, leading investigators to question people who are believed to have some connection to the SUV.

One such person made several phone calls overseas, but a senior official says it isn't yet known whether the calls had anything to do with the attempted bombing. 

"We live in an international society," the official said. "The calls may be completely innocent."

The official declined to say what the connection was to the car and how it was traced. But it shows that investigators are pursuing what they believe to be promising leads.

The Washington Post reported the following with this headline: "Officials increasingly see international plot in Times Square bomb attempt."
