Their names were flashed around the world as suicide hijackers who carried out the attacks on America. But yesterday four innocent men told how their identities had been stolen by Osama bin Laden's teams to cover their tracks. The men - all from Saudi Arabia - spoke of their shock at being mistakenly named by the FBI as suicide terrorists. None of the four was in the United States on September 11 and all are alive in their home country. The FBI released the list of 19 suicide terrorists three days after the attacks. The Saudi Airlines pilot, Saeed Al-Ghamdi, 25, and Abdulaziz Al-Omari, an engineer from Riyadh, are furious that the hijackers' personal details" - including name, place, date of birth and occupation - matched their own. The other two men accused of being terrorists are Salem Al-Hamzi and Ahmed Al-Nami. Mr Al-Hamzi is 26 and had just returned to work at a petrochemical complex in the industrial eastern city of Yanbou ... when the hijackers struck. Mr Al-Nami, 33, from Riyadh, an administrative supervisor with Saudi Arabian Airlines, said that he was in Riyadh when the terrorists struck. The FBI admitted that there was some doubt about the identities of some of the suspects. A spokesman said: "The identification process has been complicated by the fact that many Arabic family names are similar. It is also possible that the hijackers used false identities." The spokesman declined to say whether the FBI would apologise but added: "If we have made mistakes then obviously that would be regrettable."
