NY, DC oficials chase unconfirmed al-Qaida bomb threat on eve of 9/11

WASHINGTON (AP) — U.S. counterterrorism officials are chasing a credible but unconfirmed al-Qaida threat to set off a car bomb on bridges or tunnels in New York City or Washington. It was the first word of an "active plot" timed to coincide with the somber commemoration of the terror group's 9/11 attacks a decade ago that killed nearly 3,000 people.
