Summary from wiki:

In September, 2001, The New York Times and Israeli newspaper Haaretz reported that four hours after the attack, the FBI arrested five Israelis who had been filming the smoking skyline from the roof of a white van in the parking lot of an apartment building, for “puzzling behavior”. They were charged with illegally residing in the United States and working there without permits. The Israelis were said to have been videotaping the disaster with what was interpreted as cries of “joy and mockery”.[56][57] Police found the van and a search revealed $4,700 in cash hidden, along with foreign passports and a boxcutter which aroused suspicions and led to the detention of the occupants. The men were held in detention for more than 2 months, during which time they were subjected to interrogation and lie detector tests, before being deported back to Israel; one of the men (Paul Kurzberg) refused to take the test for 10 weeks, and then failed it.[58]

The five men worked at the company Urban Moving Systems, owned and operated by Dominick Suter. After the men were arrested the FBI searched their offices and questioned Suter, however Suter fled to Israel before he could be questioned further. Eventually, Suter’s name appeared on the May 2002 FBI Suspect List, along with the Sept. 11 hijackers and other suspected extremists.[59]

According to a former CIA chief of operations for counterterrorism Vince Cannistraro, there was speculation that Urban Moving Systems may have been a front for an intelligence operation investigating fund-raising networks channeling money to Hamas and Islamic Jihad. On March 15, 2002, The Forward claimed that the FBI had concluded that the van’s driver, Paul Kurzberg, and his brother Sivan, were indeed Mossad operatives, who were in America “spying on local Arabs”.[60] ABC news cited this report on June 21, 2002, adding that the FBI had concluded that the five Israelis had no foreknowledge of the attacks.[61]

In March, 2001, the US Office of the National Counterintelligence Executive had issued a warning about people identifying themselves as “Israeli art students” attempting to bypass security and gain entry to federal buildings, and even to the private residences of senior federal officials. A French intelligence agency later noted “according to the FBI, Arab terrorists and suspected terror cells lived in Phoenix, Arizona, as well as in Miami and Hollywood, Florida, from December 2000 to April 2001 in direct proximity to the Israeli spy cells”. The report contended that Mossad agents were spying on Mohammed Atta and Marwan al-Shehi, two of leaders of the 9/11 hijack teams.[62][63][64][65] In 2002 several officials dismissed reports of a spy ring and said the allegations were made by a Drug Enforcement Agency who was angry his theories had been dismissed.[66]
