As my colleague Robert Worth reported, Dubai’s police chief said on Monday that an 11-person team of trained killers with European passports carried out the mysterious assassination of a senior Hamas official last month in a Dubai hotel. In addition to releasing the names and photographs of the 11 suspects, the chief, Lt. Gen. Dahi Khalfan al-Tamim, told reporters that security camera video obtained by his investigators showed the team at work in Dubai in the hours leading up to the assassination in a luxury hotel last month.

On Tuesday, a newspaper Web site in Dubai published the video released by the authorities, which appears to show the suspects following the Hamas official, Mahmoud al-Mabhouh; changing into disguises; and spending a lot of time on the second floor of the hotel where the murder took place. The video, embedded below, was edited by the Dubai police and includes titles that explain their interpretation of the movements of the 11 suspects before, during and after the assassination.

Readers with less time may want to watch this video report from Al Jazeera, which includes key portions of the footage and shows some of the news conference at which it was presented. Britain’s ITN News reported that the victim’s brother blamed the Israeli intelligence service Mossad for the assassination.

In a report from Dubai, Alex Thompson of Britain’s Channel 4 News said that authorities there are so outraged by the assassination plot that they have sworn to issue a warrant for the arrest of Israel’s prime minister, Benjamin Netanyahu, if the killing can be traced back to Mossad.

On Tuesday, Emirates News Agency reports, Dubai issued international arrest warrants for the 11 suspects, who all traveled with European passports that appear to have been forged.

Ireland’s Foreign Ministry issued a statement saying that three of the suspects said to have used Irish passports do not exist, The Irish Times reported. The ministry added that the passport numbers were obviously fake, since they had the wrong number of digits and contained no letters, as genuine Irish documents do.

According to Julian Borger and Adam Gabbatt of The Guardian, “British officials said today that the British passports used by six suspects in the assassination of a Hamas ­commander in Dubai were forgeries, and that the suspected assassins are not British nationals.”

German officials told The Associated Press that the number on a passport used by a suspect named Michael Bodenheimer, who traveled to Dubai from Frankfurt and left for Hong Kong three hours after the killing, was too short.

The French foreign ministry told AFP on Tuesday that it was “not able to confirm the nationality” of the one suspect said to have used a French passport.

AFP also reports that Dubai police said they are questioning two Palestinians in connection with their investigation. Dubai’s police chief said that both men are residents of the United Arab Emirates who “fled to Jordan” after the killing and were extradited three days ago.

In Israel, a man with the same name as one of the suspects identified by the Dubai police as a British national who was a member of the team told Reuters that his identity must have been stolen.

Speaking in British-accented English, Melvyn Adam Mildiner, resident of a town near Jerusalem, told Reuters he had nothing to do with the assassination and had never been to Dubai. “I woke up this morning to a world of fun,” he said in a sarcastic tone, after Israeli newspapers splashed names and photos of the suspects distributed by Dubai. “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,” he said in a telephone interview.

Writing in the Israeli newspaper Haaretz, Yossi Melman observed that the actions of the 11 suspects shown on the security camera footage were similar to methods apparently used by Israeli intelligence agents. Mr. Melman wrote:
