The ceremony began as police remain hunting for three stolen vans belonging to construction companies doing work in or around the World Trade Center site.
The news comes as the identity of one of the three alleged terrorists plotting a possible attack was revealed.
An image of American-born 22-year-old Jude Kenan Mohammad is on the FBI’s Ten Most Wanted list for previous links to terrorism.
He has now been linked to what officials have called a credible but unconfirmed al-Qaeda threat to set off a car bomb on bridges or tunnels in New York City or Washington D.C.
The Wall Street Journal reported Mohammad is among three al-Qaeda leaders that investigators believe pose a particular threat because they have lived in the U.S.
Should that mission prove impossible, the attackers have been told to simply cause as much destruction as they can.
The first vehicle, a dark green Chevrolet van with a yellow turret light, was stolen from the Long Island Expressway on September 1.
On September 2, three men broke into a construction yard before loading $70,000 worth of tools into another stolen van and off with a third vehicle.
NYPD Deputy Commissioner Paul Browne said: ‘This may very well be industrial savvy thieves looking to steal expensive construction equipment, but it’s receiving greater scrutiny because of the threat environment.’
President Obama met with his national security team on Saturday, but the White House released no new information about possible threats.
A statement said that counterterrorism efforts were working well and would not ease in the weeks and months ahead.
