Khalid Muhammad Abdallah al-Mihdhar (; also transliterated as AL Mihdhar; May 16, 1975 – September 11, 2001) was a Saudi terrorist hijacker. He was one of the five hijackers of American Airlines Flight 77, which was flown into the Pentagon as part of the September 11 attacks.

Al-Mihdhar was born in Saudi Arabia. In early 1999, he traveled to Afghanistan where, as an experienced and respected jihadist, he was selected by Osama bin Laden to participate in the attacks. Al-Mihdhar arrived in California with fellow hijacker Nawaf al-Hazmi in January 2000, after traveling to Malaysia for the Kuala Lumpur al-Qaeda Summit. At this point, the Central Intelligence Agency (CIA) was aware of al-Mihdhar, and he was photographed in Malaysia with another al-Qaeda member who was involved in the bombing of the USS Cole. The CIA did not inform the Federal Bureau of Investigation (FBI) when it learned that al-Mihdhar and al-Hazmi had entered the United States, and al-Mihdhar was not placed on any watchlists until late August 2001.

Upon arriving in San Diego County, California, al-Mihdhar and al-Hazmi were to train as pilots, but spoke English poorly and did not do well with flight lessons. In June 2000, al-Mihdhar left the United States for Yemen, leaving al-Hazmi behind in San Diego. Al-Mihdhar spent some time in Afghanistan in early 2001 and returned to the United States in early July 2001. He stayed in New Jersey in July and August, before arriving in the Washington, D.C., area at the beginning of September.

On the morning of 11 September 2001, al-Mihdhar boarded American Flight 77 and assisted in the hijacking of the plane, which was hijacked approximately 30 minutes after takeoff. Al-Mihdhar and his team of hijackers then deliberately crashed the plane into the Pentagon, killing themselves and all 59 people aboard the flight, in addition to 125 on the ground.

Background Al-Mihdhar was born on May 16, 1975, in Mecca, Saudi Arabia, to a prominent family that belonged to the Quraysh tribe of Mecca.Videotape of recorded will of Abdulaziz al-Omari and others Little is known about his life before the age of 20, when he and childhood friend Nawaf al-Hazmi went to Bosnia and Herzegovina to fight with the mujahideen in the Bosnian War.9/11 Commission Report, Chapter 5.2, pp. 153–159McDermott (2005), p. 191 After the war, al-Mihdhar and al-Hazmi went to Afghanistan where they fought alongside the Taliban against the Northern Alliance,Wright (2006), p. 309 and al-Qaeda would later dub al-Hazmi his "second in command". In 1997, al-Mihdhar told his family that he was leaving to fight in Chechnya, though it is not certain that he actually went to Chechnya.Burke (2004), p. 237 The same year, both men attracted the attention of Saudi Intelligence, who believed they were involved in arms smuggling, and the following year they were eyed as possible collaborators in the 1998 United States embassy bombings in East Africa after it emerged that Mohamed Rashed Daoud Al-Owhali had given the FBI the phone number of al-Mihdhar's father-in-law; 967-1-200578, which turned out to be a key communications hub for al-Qaeda militants, and eventually tipped off the Americans about the upcoming Kuala Lumpur al-Qaeda Summit.Mayer, Jane, "The Dark Side", 2008.

In the late 1990s, al-Mihdhar married Hoda al-Hada, who was the sister of a comrade from Yemen, and they had two daughters. Through marriage, al-Mihdhar was related to a number of individuals involved with al-Qaeda in some way. Al-Mihdhar's father-in-law, Ahmad Mohammad Ali al-Hada, helped facilitate al-Qaeda communications in Yemen, and in late 2001, al-Mihdhar's brother-in-law, Ahmed al-Darbi, was captured in Azerbaijan and sent to Guantanamo Bay on charges of supporting a plot to bomb ships in the Strait of Hormuz.Office of the Assistant Secretary of Defense, Guantanamo Detainee Charged (ISN 768), 21 December 2007

Selection for the attacks

In Spring 1999, al-Qaeda founder Osama bin Laden committed to support the 9/11 attacks plot, which was largely organized by prominent al-Qaeda member Khalid Sheikh Mohammed. Al-Mihdhar and al-Hazmi were among the first group of participants selected for the operation, along with Tawfiq bin Attash and Abu Bara al Yemeni, al-Qaeda members from Yemen. Al-Mihdhar, who had spent time in al-Qaeda camps in the 1990s, was known to and highly regarded by Bin Laden. Al-Mihdhar was so eager to participate in jihad operations in the United States that he had already obtained a one-year B-1/B-2 (tourist/business) multiple-entry visa from the consulate in Jeddah, Saudi Arabia, on April 7, 1999, one day after obtaining a new passport.9/11 and Terrorist Travel, pp. 9–10 Al-Mihdhar listed the Los Angeles Sheraton as his intended destination.FBI Hijackers' Timeline, p. 40

Once selected, al-Mihdhar and al-Hazmi were sent to the Mes Aynak training camp in Afghanistan. In late 1999, al-Hazmi, bin Attash and al Yemeni went to Karachi, Pakistan to see Mohammed, who instructed them on Western culture and travel; however, al-Mihdhar did not go to Karachi, instead returning to Yemen. He was known as Sinaan during the preparations.

2000

Malaysia summit

The CIA was aware of al-Mihdhar and al-Hazmi's involvement with al-Qaeda, having been informed by Saudi intelligence during a 1999 meeting in Riyadh. Based on information uncovered by the FBI in the 1998 United States embassy bombings case, the National Security Agency (NSA) began tracking the communications of Hada, al-Mihdhar's father-in-law. In late 1999, the NSA informed the CIA of an upcoming meeting in Malaysia, which Hada mentioned would involve "Khalid", "Nawaf", and "Salem", who was al-Hazmi's younger brother, Salem al-Hazmi.

On 4 January 2000, al-Mihdhar left Yemen and flew to Dubai, United Arab Emirates, where he spent the night. The CIA broke into his hotel room and photocopied his passport, which gave them his full name, birth information and passport number for the first time, and alerted them that he held an entry visa to the United States. The photocopy was sent to the CIA's Alec Station, which was tracking al-Qaeda.

On 5 January 2000, al-Mihdhar traveled to Kuala Lumpur, where he joined al-Hazmi, bin Attash, and al-Yemeni, who were all arriving from Pakistan. Hamburg cell member Ramzi bin al-Shibh was also at the summit, and Mohammed possibly attended.Fouda and Fielding (2003), pp. 129–130 The group was in Malaysia to meet with Hambali, the leader of Jemaah Islamiyah, an Asian al-Qaeda affiliate. During the Kuala Lumpur al-Qaeda Summit, many key details of the 9/11 attacks may have been arranged. At the time, the attacks plot had an additional component involving hijacking aircraft in Asia, as well as in the United States. Bin Attash and al-Yemeni were slated for this part of the plot. However, it was later canceled by bin Laden for being too difficult to coordinate with United States operations.

In Malaysia, the group stayed with Yazid Sufaat, a local Jemaah Islamiyah member, who provided accommodation at Hambali's request. Both al-Mihdhar and al-Hazmi were secretly photographed at the meeting by Malaysian authorities, whom the CIA had asked to provide surveillance. The Malaysians reported that al-Mihdhar spoke at length with bin Attash, and he met with Fahd al-Quso and others who were later involved in the USS Cole bombing. After the meeting, al-Mihdhar and al-Hazmi traveled to Bangkok, Thailand, on 8 January and left a week later on 15 January for the United States.FBI Hijackers' Timeline, p. 52

United States entry

On 15 January 2000, al-Mihdhar and al-Hazmi arrived at Los Angeles International Airport from Bangkok and were admitted as tourists for a period of six months.9/11 and Terror Travel, p. 10 On 1 February 2000–17 days upon entering the United States—the two men encountered Omar al-Bayoumi and Caysan Bin Don at a halal food restaurant on Venice Boulevard in Culver City.9/11 Commission Report, 9/11 Commission, p. 217 Al-Bayoumi claimed he was merely being charitable in assisting the two seemingly out-of-place Muslims with moving to San Diego, where he helped them find an apartment near his own, co-signed their lease, and gave them $1,500 to help pay their rent. Mohammed later claimed that he suggested San Diego as their destination, based on information gleaned from a San Diego phone book that listed language and flight schools. Mohammed also recommended that the two seek assistance from the local Muslim community, since neither spoke English nor had experience with Western culture.

While in San Diego, witnesses told the FBI he and al-Hazmi had a close relationship with Anwar al-Awlaki, an imam who served as their spiritual advisor.Eckert, Toby, and Stern, Marcus, "9/11 investigators baffled FBI cleared 3 ex-San Diegans", The San Diego Union, 11 September 2003, 30 November 2009 Authorities say the two regularly attended the Masjid Ar-Ribat al-Islami mosque al-Awlaki led in San Diego, and al-Awlaki had many closed-door meetings with them, which led investigators to believe al-Awlaki knew about the 9/11 attacks in advance.

In early February 2000, al-Mihdhar and al-Hazmi rented an apartment at the Parkwood Apartments complex in the Clairemont Mesa area of San Diego, and al-Mihdhar purchased a used 1988 Toyota Corolla.FBI Hijackers' Timeline, pp. 54–55 Neighbors thought that al-Mihdhar and al-Hazmi were odd because months passed without the men getting any furniture, and they slept on mattresses on the floor, yet they carried briefcases, were frequently on their mobile phones, and were occasionally picked up by a limousine.Aust (2002), pp. 17–18 Those who met al-Mihdhar in San Diego described him as "dark and brooding, with a disdain for American culture".Fouda and Fielding (2003), p. 136 Neighbors also said that the pair constantly played flight simulator games.

Al-Mihdhar and al-Hazmi took flight lessons on 5 May 2000, at the Sorbi Flying Club in San Diego, with al-Mihdhar flying an aircraft for 42 minutes. They took additional lessons on 10 May;FBI Hijackers' Timeline, pp. 63–64 however, with poor English skills, they did not do well with flight lessons. Al-Mihdhar and Al-Hazmi raised some suspicion when they offered extra money to their flight instructor, Rick Garza, if he would train them to fly jets. Garza refused the offer but did not report them to authorities. After the 9/11 attacks, Garza described the two men as "impatient students" who "wanted to learn to fly jets, specifically Boeings".

Return to Yemen Al-Mihdhar and al-Hazmi moved out of the Parkwood Apartments at the end of May 2000, and al-Mihdhar transferred registration for the Toyota Corolla to al-Hazmi.FBI Hijackers' Timeline, p. 67 On 10 June 2000, al-Mihdhar left the United States and returned to Yemen to visit his wife, against the wishes of Mohammed who wanted him to remain in the United States to help al-Hazmi adapt.9/11 and Terror Travel, p. 11Substitution for the Testimony of KSM at the trial of Zacarias Moussaoui Mohammed was so angered by this that he decided to remove al-Mihdhar from the 9/11 plot, but he was overruled by bin Laden. Al-Mihdhar remained part of the plot as a muscle hijacker, who would help take over the aircraft.9/11 Commission Report, Chapter 7.2 – The Attack Looms, First Arrivals in California, pp. 215–222 On 12 October 2000, the USS Cole was bombed by a small boat loaded with explosives. After the bombing, Yemeni Prime Minister Abdul Karim al-Iryani reported that al-Mihdhar had been one of the key planners of the attack and had been in the country at the time of the attacks.Smith (2005), p. 60 In late 2000, al-Mihdhar was back in Saudi Arabia, staying with a cousin in Mecca.
