Abdulaziz al-Omari (, , also transliterated as Alomari or al-Umari; May 28, 1979 – September 11, 2001) was a Saudi terrorist who was one of five hijackers of American Airlines Flight 11 as part of the September 11 attacks in 2001. Prior to the terrorist attack, al-Omari was an airport security guard and imam. Al-Omari arrived in the United States in June 2001, on a tourist visa, obtained through the Visa Express program. On September 11, 2001, al-Omari boarded American Airlines Flight 11 and assisted in the hijacking of the plane, which was crashed into the North Tower of the World Trade Center, as part of the coordinated attacks. Early life and education Little is known about al-Omari's life, and it is unclear whether some information refers to Omari or another person by that name. He had used the birth date May 28, 1979. It is alleged al-Omari graduated with honors from high school, attained a degree from Imam Muhammad ibn Saud Islamic University, was married and had a daughter briefly before the attacks. Career Al-Omari is alleged to have often served as an imam at his mosque in Saudi Arabia and is believed by American authorities to have been a student of Saudi cleric Sulaiman Al-Alwan, whose mosque is located in Al-Qassim Province. According to Walid bin Attash, al-Omari was one of a group of future hijackers who provided security at Kandahar airport after their basic training at an al-Qaeda camp. During the 2000 Al Qaeda Summit in Kuala Lumpur, American authorities state that immigration records show that a person named Abdulaziz al-Omari was visiting the country, although they say they are not sure that this was the same person. In the autumn of 2001, after the September 11 attacks, al Jazeera television broadcast a tape they claim was made by al-Omari. The speaker made a farewell suicide video. In it he read, "I am writing this with my full conscience and I am writing this in expectation of the end, which is near. . . God praise everybody who trained and helped me, namely the leader Sheikh Osama bin Laden." According to FBI director Robert Mueller and the 9/11 Commission, al-Omari entered the United States through a Dubai flight on June 29, 2001, with Salem al-Hazmi, landing in New York. He had used the controversial Visa Express program to gain entry. He apparently stayed with several other hijackers
