A developing story out of Washington, where federal officials reportedly have uncovered a "credible threat" of an al-Qaeda attack in New York City or Washington, D.C. on or around the 10th anniversary of 9/11.
ABC News is reporting that three people entered the United States from Afghanistan, possibly via another country, sometime in August with the intent of pulling off a "vehicle-borne attack," according to senior officials.
One of those officials added that at least two rental trucks -- one from Penske and one from Budget -- were being sought nationwide. The Budget GMC truck and the Penske GMC both were missing from locations in Kansas City, Missouri. It was not immediately known if that search was connected to the plot.
Officials say the information is "very specific," that "it seems like the information has been worked for a while."
Federal officials are said to be working on an urgent bulletin to send to law enforcement all over the country.
Fox News reports that the names of the suspected terrorists are not known and that the threat is "specific enough to elicit worry," according to one U.S. official.
"As we know from the intelligence gathered from the [bin Laden] raid, al-Qaeda has shown an interest in important dates and anniversaries, such as 9/11," Department of Homeland Security spokesman Matt Chandler said in a statement. "In this instance, it's accurate that there is specific, credible but unconfirmed threat information."
