Dubai authorities have released extensive footage from surveillance cameras that allegedly shows the movements of a professional 11-person assassination team in the hours before and after a top Hamas leader was killed last month in a hotel room.

The footage, taken from cameras at the Dubai airport and several luxury hotels, follows the activities of 10 men and one woman as they arrived in Dubai on various European passports and moved among hotels and a shopping center, changing into disguises at one point, during the hours before Mahmoud al-Mabhouh was killed.

Al-Mabhouh, 48, was a founder of Hamas’ military wing. He was believed to be behind the abduction of two Israeli soldiers in 1989 and said to be a liaison for smuggling weapons from Iran to Gaza. He had survived several assassination attempts.

He was found dead in room 230 at the Al-Bustan Rotana hotel on January 20. The door on al-Mabhouh’s room was latched and chained from the inside, and there was no blood evidence. An initial report indicated that he died from sudden high blood pressure in the brain. Subsequent reports have suggested he was electrocuted or strangled.

An investigation into hotel records and surveillance tapes uncovered the suspicious activities of a group of Westerners, most of them wearing baseball caps. They staked out al-Mabhouh’s room on the hotel’s second floor, met clandestinely in various locations, disguised themselves and left the hotel briskly after the deed was done. Investigators believe the assassins may have reprogrammed the electronic lock on al-Mabhouh’s door to gain entry.

Hamas has accused the Mossad, Israel’s secretive intelligence service, of masterminding the assassination.

In the 27-minute video, released by Gulf News TV, some of the suspected assassins arrive on separate flights to Dubai early the morning the murder took place. The footage shows some of them meeting up briefly in a shopping mall and checking into and out of hotels during the setup stage. One of the suspects, a bald male, enters a hotel and exits wearing a brown wig and glasses. Later, a woman identified as an Irish national named Gail Folliard, is shown checking into her hotel wearing glasses and a ponytail, then entering the same location where the male suspect changed his appearance. She exits that location wearing a brunette wig.

When al-Mabhouh arrives at his hotel around 3 p.m. on the 19th, the footage captures two of the suspects, dressed in tennis gear, getting into the same elevator with him to follow him to his hotel room. The two suspects later checked into the room across the hall from him, according to Dubai police.

Around 8 p.m., the cameras catch some of the team members in the elevator lobby of al-Mabhouh’s floor while he is out of the hotel for a bit. While they’re standing there keeping watch, another team is apparently trying to gain entry to the victim’s room. During this time, a tourist steps off the elevator, putting the operation in jeopardy, until one of the team members distracts the tourist. A note on the video indicates that, according to the hotel’s computer logs, someone tried to reprogram al-Mabhouh’s electronic door lock during this time.

Al-Mabhouh returned to the hotel around 8:25 p.m and passed the female suspect, Folliard, in the hallway on the way to his room. The killing itself took only 10 minutes around 8:30 p.m., Dubai Police Chief Lt. Gen. Dhahi Khalfan Tamim told the Israeli newspaper Ha’Aretz. Four assassins allegedly entered the victim’s hotel room while he was out, using an electronic device to unlock his door, and waited for him to return. Hotel staff discovered his body around 1:30 p.m. on the 20th after failing to reach him on the phone. By then, he’d been dead about 17 hours, and the alleged assassins were long gone.

Oddly, although there is surveillance tape showing the closed doors of some of the rooms near al-Mahbouh’s hotel room when he first checked in, there is no tape showing the assassins entering or leaving the room or walking down that hallway at the time of the assassination. A map of the hotel shown in the video, indicates that the only surveillance camera in that hallway was located one door down from the victim’s room and pointed away from his door toward what appears to be a stairwell.

Following the assassination, the suspects left the hotel quickly and were tracked scattering to different parts of the globe, including Hong Kong, France, Switzerland, Germany and South Africa.

Authorities say the suspects paid for everything in cash and used special communication devices to avoid surveillance. They never made direct calls to one another, as far as authorities could determine. They did, however, make a number of calls to Austria, which authorities believe may have been the location of their command-and-control center.

Within 24 hours after the murder, Dubai investigators reportedly identified the aliases the alleged assassins used on their forged passports. The nationalities on the documents indicated that six of them are British, three are Irish, one is French and one is German. Although the videos show a second woman identified as part of the surveillance team, only one woman — Folliard — is listed among the suspects.

British, Irish and French authorities have indicated that the passports used by the alleged assassins showed obvious signs of forgery. The Irish passport numbers used by suspects Gail Folliard, Evan Dennings and Kevin Daveron, for example, contain no letters and have the wrong number of digits.

At least five Israelis share the same names used by the alleged assassins. One of the names matches a man living near Jerusalem named Melvyn Adam Mildiner. Mildiner, a British national, says his identity was stolen and that he had nothing to do with the assassination. The picture of him that was released by Dubai authorities does not completely match him, Reuters reports.

“I woke up this morning to a world of fun,” he told Reuters after Israeli newspapers published the names and photos of the suspects identified by Dubai authorities. “I am obviously angry, upset and scared — any number of things. And I’m looking into what I can do to try to sort things out and clear my name. I don’t know how this happened or who chose my name or why, but hopefully we’ll find out soon.”

The Mossad is noted for its stealth assassinations. The intelligence service was responsible for tracking down and killing Palestinian militants who murdered Israeli athletes at the 1972 Olympics in Munich, as depicted in the Steven Spielberg movie Munich.

The Mossad was also responsible in 1986 for capturing Mordechai Vanunu, a worker at Israel’s Dimona nuclear plant who had planned to disclose information about Israel’s secret nuclear weapons program to the Sunday Times newspaper in the United Kingdom. A female Mossad agent posing as a tourist in the UK lured the shy Vanunu out of London to Rome, where he was drugged and kidnapped and returned to Israel for a secret trial. He spent 18 years in prison and was released in 2004.
