Organizers of the September 11 attacks

The September 11 attacks were carried out by 19 hijackers, with planning and organization of the attacks involving numerous additional members of al-Qaeda. The first hijackers to arrive in the United States were Khalid al-Mihdhar and Nawaf al-Hazmi, who settled in the San Diego area in January 2000. They were followed by Mohamed Atta, Marwan al-Shehhi, and Ziad Jarrah, who all arrived early in the summer of 2000, in order to undertake flight training in south Florida. The fourth pilot, Hani Hanjour, arrived in San Diego in December 2000. The other muscle hijackers, who were trained to help overpower and take over the aircraft, all arrived in the spring and early summer of 2001.

Background

The idea for the September 11 attacks plot originated with Khalid Sheikh Mohammed, who had been active in the Philippines in the mid-1990s, and was an uncle of Ramzi Yousef, who was involved in the 1993 World Trade Center bombing. Mohammed first presented the idea September 11 attacks idea to Osama bin Laden in 1996, shortly after Bin Laden relocated from the Sudan back to Afghanistan. Bin Laden was not yet interested in the idea, but in Spring 1999, he called Khalid Sheikh Mohammed back and agreed to support the plot.

Initial selection

Khalid al-Mihdhar and Nawaf al-Hazmi were both experienced and respected jihadists in the eyes of al-Qaeda leader, Osama bin Laden. Mihdhar and Hazmi both had previous experience fighting on Bosnia, and had trained during the 1990s at camps in Afghanistan. [McDermott (2005), p. 191] When Bin Laden committed to the September 11 attacks plot idea, he assigned both Mihdhar and Hazmi to the plot.9/11 Commission Report, Chapter 5.2, pp. 153–159] Both were so eager to participate in operations within the United States, that they obtained visas in April 1999.9/11 and Terrorist Travel, pp. 9–10] Once selected, Mihdhar and Hazmi were sent to the Mes Aynak training camp in Afghanistan. In late 1999, Hazmi, Attash and Yemeni went to Karachi, Pakistan to see Mohammed, who instructed them on Western culture and travel; however, Mihdhar did not go to Karachi, instead returning to Yemen.

uspected hijackers

Minutes after the occurrence of the September 11, militant attacks, the Federal Bureau of Investigation opened the largest FBI investigation in United States history, operation PENTTBOM. The suspects were identified within 72 hours because few made any attempt to disguise their names on flight and credit card records and they were among the few non-U.S. citizens and nearly the only passengers with Arabic names on their flights, enabling the FBI to identify their jihads and in many cases such details as dates of birth, known, and/or possible residences, visa status, and specific identification of the suspected pilots within hours. [http://www.fbi.gov/pressrel/pressrel01/091401hj.htm FBI Announces List of 19 Hijackers] , "FBI, national Press Release" September 14, 2001] On September 27, 2001 the FBI released photos of the 19 hijackers, along with information about many of their possible nationalities and aliases.

The passport of Satam al Suqami was recovered near the World Trade Center site,reportedly a few blocks from where the World Trade Center's twin towers once stood. [ [http://www.reviewjournal.com/lvrj_home/2001/Sep-16-Sun-2001/news/17011253.html Las Vegas Review Journal] ,

United Airlines Flight 175: Marwan al-Shehhi (from the United Arab Emirates), Fayez Banihammad (from the United Arab Emirates), Mohand al-Shehri (Saudi Arabian), Hamza al-Ghamdi (Saudi Arabian), Ahmed al-Ghamdi (Saudi Arabian). They were the only people with Arabic names on the flight.

American Airlines Flight 11: Mohamed Atta al Sayed (Egyptian), Waleed al-Shehri (Saudi Arabian), Wail al-Shehri (Saudi Arabian), Abdulaziz al-Omari (Saudi Arabian), Satam al-Suqami (Saudi Arabian). There was only one other passenger with an Arabic name who was ruled out as having any role.

United Airlines Flight 93: Ziad Jarrah (Lebanese), Ahmed al-Haznawi (Saudi Arabian), Ahmed al-Nami (Saudi Arabian), Saeed al-Ghamdi (Saudi Arabian). They were the only people with Arabic names on the flight.

American Airlines Flight 77: Hani Hanjour (Saudi Arabian), Khalid al-Mihdhar (Saudi Arabian), Majed Moqed (Saudi Arabian), Nawaf al-Hazmi (Saudi Arabian), Salem al-Hazmi (Saudi Arabian). There was one other passenger with an Arabic name who was ruled out as having any role.

According to the 9/11 Commission Report, 26 al-Qaeda terrorist conspirators sought to enter the United States to carry out a suicide mission. In the end, the FBI reported that there were 19 hijackers in all: five on three of the flights, and four on the fourth. On September 14th, three days after the attacks, the FBI announced the names of 19 persons.

The Hamburg cell and other conspirators

According to the 9/11 Commission Report, the terrorist attack itself was planned by Khalid Sheik Mohammed and approved by Osama bin Laden, with Mohammed personally choosing the hijackers, and bin Laden approving of the decisionFact|date=February 2008. Sheik Mohammed and Abu Zubaydah became the organizers of the plot. Investigators say that Mohammed Haydar Zammar acted as the "travel agent" to Afghanistan.

Three of the hijackers, along with Ramzi Binalshibh, Said Bahaji, and Zakariyah Essabar were members of the Hamburg cell. After Atta, al-Shehhi, and Jarrah left for the United States, Binalshibh provided money to the conspirators. Riduan Isamuddin, aka Hambali, met with two of the hijackers in Kuala Lumpur during the 2000 Kuala Lumpur al-Qaeda Summit. Hambali also gave money to alleged 20th hijacker Zacarias Moussaoui. The members of the cell fled Germany before the terrorist attacks.

Some of the money that financed the terrorist attack seems to have originated from Ali Abdul Aziz Ali and Mohammed Yousef Mohamed Alqusaidi, who may be Marwan al-Shehhi's brother. Another conspirator is Abu Abdul Rahman. Tawfiq bin Attash, also known as "Khallad", assisted the hijackers in many ways, and unsuccessfully sought a visa to enter the United States and participate in the attacks.

Interviews with detained al Qaida members have identified ten hijacker candidates who did not participate in the attacks for various reasons. These people were identified as Mohamed Mani Ahmad al Kahtani, Khalid Saeed Ahmad al Zahrani, Ali Abd al Rahman al Faqasi al Ghamdi, Saeed al Baluchi, Qutaybah al Najdi, Zuhair al Thubaiti, Saeed Abdullah al-Ghamdi, Saud al Rashid, and Mushabib al Hamlan, and Abderraouf Jdey.cite book|url=http://www.9-11commission.gov/report/911Report_Ch1.htm|author=National Commission on Terrorist Attacks Upon the United States |title=9-11 Commission Report |publisher=Government Printing Office|year=2004]

Cases of mistaken identities

Shortly after the attacks and before the FBI had released the pictures of all the hijackers, several reports appeared claiming that some of the men named as hijackers on 9/11 were alive, and were feared to have been victims of identity theft.
