Mohammed Mani Ahmad al-Qahtani () (sometimes transliterated as al-Kahtani) (born November 19, 1975) is a Saudi citizen who was detained as an al-Qaeda operative for 20 years in the United States's Guantanamo Bay detention camps in Cuba. Qahtani allegedly tried to enter the United States to take part in the September 11 attacks as the 20th hijacker and was due to be onboard United Airlines Flight 93 along with the four other hijackers. He was refused entry due to suspicions that he was trying to illegally immigrate. He was later captured in Afghanistan in the battle of Tora Bora in December 2001. After military commissions were authorized by Congress, in February 2008, Qahtani was charged on numerous counts. In May, the charges were dropped without prejudice. New charges were filed against him in November 2008 and dropped in January 2009, as evidence had been obtained through torture and was inadmissible in court. This was the first time an official of the Bush administration had admitted any torture of detainees at Guantanamo. In a Washington Post interview in January 2009, Susan Crawford of the Department of Defense said "we tortured Qahtani", saying that the U.S. government had so abused Qahtani through isolation, sleep deprivation, forced nudity and exposure to cold that he was in a "life-threatening condition." On March 6, 2022, Qahtani was airlifted from Guantanamo Bay by the U.S. military and flown back to Saudi Arabia to a mental health treatment facility after 20 years in American custody. His release was announced by the U.S. Department of Defense the next day. Early life Mohammed al-Qahtani was born on 19 November 1975 in Kharj, Saudi Arabia. He is a Saudi national from a large Sunni family. His father served as a police officer for 28 years. His mother remained at home to raise their twelve children. He has seven brothers and four sisters, who range in age from 14 to 42 years of age. Denied entry by US immigration On August 3, 2001, Qahtani at the age of 26 flew into Orlando, Florida, from Dubai. He was questioned by immigration agent José Meléndez-Pérez, who was dubious that he could support himself with only $2,800 cash to his name, and suspicious that he intended to become an illegal immigrant, as he was using a one-way ticket. He was sent back to Dubai, and subsequently returned to Saudi Arabia. Transfer to Guantanamo Captured
