Israeli citizens who learned that their names had been tied to passports used by the hit squad that assassinated Hamas commander Mahmoud al-Mabhouh expressed shock on Wednesday at the findings.

Dubai authorities have said they are "99 percent" certain the Mossad, Israel's spy agency, was behind the killing of Mabhouh, a senior Hamas commander from Gaza allegedly suffocated to death in his Dubai hotel room. Israeli officials, however, have said that there is no proof connecting Mossad to the killing.

Philip Carr, a father of five from the town of Beit Shemesh, near Jerusalem, said he was "in shock" after hearing the news that one of the suspects had allegedly used his identity.

Carr confirmed he had a British passport, which he said he had only used once to travel abroad, because he also had Israeli and South African passports. He said he was born in Britain, but grew up in South Africa, before immigrating to Israel.

Carr, a 36-year-old technician, said he was recovering from sinusitis when he heard that his name and British passport name appeared on the new list of suspects.

"I've been in bed for two days with a splitting headache and a temperature. And then I get a phone call that I am on an international watch list. Fantastic, huh?" Carr told The Associated Press on the phone from his home.

"That picture is certainly not me. He's wearing glasses. I've got 20-20 vision," said Carr, who immigrated to Israel eight years ago.

Mark Daniel Sklar, whose name was also on a British passport used, according to Dubai police, by one of the suspects, also said he had nothing to do with the Dubai operation.

"Of course I don't. No! No! No!," he told Channel 10 news.

"In a while it'll be 7 million, all of Israel's inhabitants," he quipped.

Another Israeli man named Stephen Kayat, meanwhile, said he only had one passport, an Israeli one, with that name and that he was not the Stephen Keith Drake whose name was used in one of the allegedly fake British passports.

Some seven of the 11 suspects previously named by Dubai police are also said to have namesakes in Israel.

The 15 new names brought to 26 the number of suspects in the case after police had identified 11 suspects earlier this month.

Twelve held British passports, six had Irish ones, four French, three Australian and one suspect carried German documents.
