From the FBI report:
The Israelis were observed near Liberty State Park New Jersey celebrating and photographing the World Trade Center (WTC) explosion within minutes after the WTC (Ie: The First Tower; the North Tower) was first hit by an aircraft.
It should be noted that there were inconsistencies in the statements made by (Blanked out = Yaron Shmuel) who stated that the van he was in was on the West Side Highway in New York at the time of the attack on the WTC.
However, he is clearly visible in photographs which he and other occupants in the van had taken from a roof top parking garage located at 100 Manhattan Avenue, Jersey City, New Jersey, within minutes after the first WTC building was struck by an aircraft.
[So Yaron Shmuel and Sivan Kurzberg - who, as reported by The New York Times, was shown in one photograph "holding a lighted lighter" - both appear in the photos of the happy, celebrating Israelis.]
