American spy networks have intercepted communications from a known al Qaeda operative in Pakistan that indicates plans for a potential terrorist strike in New York or Washington D.C, according to a senior U.S. official.
The communication comes from a source that has in the past provided accurate information, the official said, prompting intelligence officials to sift through communications from other known al Qaeda cells.
No corroborating has been uncovered, the official added.
The information indicates that the strike - thought to come from a vehicle-borne explosive device - is meant to coincide with the 10th anniversary of the September 11th, 2001 attack.
