WASHINGTON (AP) -- Senior U.S. counterterrorism officials say they have a general sense of who is behind the reported plot to attack New York or Washington with a car bomb on or around the 9/11 anniversary -- and who may be assigned to carry it out. But they don't have exact identities yet.
They say there's at least one U.S. citizen among the three people.
Officials say they're pursuing the three, who may be traveling to the U.S. or may already be in the country, based on detailed information received by the U.S. intelligence community.
Police in New York and Washington have increased their already-boosted staffing levels. In New York, authorities have been stopping vehicles at the 59th Street bridge today. National Guard troops are watching the crowds at Penn Station. In Washington, police officials say officers will be working 12-hour shifts, and every officer will be working this weekend. Cars that are left unattended in unusual locations may be towed.
White House officials say President Barack Obama hasn't changed his plans to visit New York's ground zero, the Pentagon, and Shanksville, Pa., on Sunday to mark the anniversary.
The nation's terror alert level has not changed, although officials were considering doing so last night.
