Known for	Mastermind behind the September 11 attacks

Khalid Sheikh Mohammed (also spelled Shaykh; born 14 April 1965), frequently referred to as KSM, is a Pakistani national affiliated with al-Qaeda and formerly served as the chief of its propaganda division. He is presently held by the United States at Guantanamo Bay, facing terrorism-related accusations, and was designated as "the main mastermind behind the September 11 attacks" in the 2004 9/11 Commission Report.

From approximately 1999 until late 2001, Mohammed directed al-Qaeda's propaganda efforts. On 1 March 2003, he was apprehended in Rawalpindi, Pakistan, through a collaborative operation between the U.S. CIA and Pakistan's ISI. After his capture, he was transferred through covert CIA detention sites in Afghanistan and Poland, where he underwent interrogation and torture. By December 2006, he was held under military custody at Guantanamo Bay.

Recognized widely as the principal planner of the September 11 attacks, Mohammed was also involved in orchestrating the Richard Reid shoe bombing attempt, the 2002 Bali bombings, the 1993 World Trade Center bombing, and the killing of Daniel Pearl, among other terrorist incidents. In February 2008, a U.S. military commission at Guantanamo charged him with war crimes and murder; if found guilty, he faced the death penalty. Nevertheless, his trial encountered controversy due to confessions obtained under torture and disputes over the admissibility of evidence.

A military judge initially scheduled Mohammed's death penalty trial for 11 January 2021; however, it was delayed because of the COVID-19 pandemic. The proceedings resumed in September 2021 but were postponed once more amid negotiations over a plea agreement. On 31 July 2024, Mohammed consented to plead guilty in return for a life sentence instead of facing a capital trial; this plea deal was rescinded two days later by Secretary of Defense Lloyd Austin. Subsequently, in November 2024, a military judge ruled that the plea agreement was "valid and enforceable."

Early life and education

Mohammed was born on 14 April 1965 in Kuwait. His father, Shaikh Muhammad Ali Dustin al-Baluchi, served as a Deobandi imam who relocated from Balochistan to Kuwait during the 1950s. Mohammed grew up in Badawiya, a district within the Fahaheel suburb of Kuwait City. He is related as uncle to Ramzi Yousef, convicted for the 1993 World Trade Center bombing, and Ammar al-Baluchi, implicated in various terror conspiracies.

In 1982, Mohammed responded to a call for jihad against Soviet forces issued by Abdul Rasul Sayyaf. At age sixteen, he became a member of the Muslim Brotherhood. After completing high school in 1983, he moved to the United States where he initially enrolled at Chowan College in North Carolina before transferring to North Carolina Agricultural and Technical State University, earning a Bachelor of Science degree in mechanical engineering in 1986.

In 1987, Mohammed traveled to Peshawar, Pakistan, to join mujahideen fighters engaged in the Soviet–Afghan War. He received training at the Sada camp under Sheikh Abdallah Azzam and contributed to al-Bunyan al-Marsous, a publication linked to Sayyaf's insurgent group. By correspondence from Punjab University in Pakistan, he obtained a master's degree in Islamic Culture and History in 1992. Around 1993, Mohammed married and moved to Qatar where he worked as a project engineer for the Qatari Ministry of Electricity and Water, marking the start of his international travel.

According to the U.S. 9/11 Commission Report, Mohammed's hostility toward the United States originated from opposition to American foreign policy supporting Israel rather than from his academic tenure. However, a 2009 Washington Post investigation based on U.S. intelligence revealed that his limited and adverse experiences during his time in America—including brief incarceration over unpaid bills—played a role in his radicalization. Intelligence assessments highlighted that his sparse interaction with Americans reinforced his perception of the U.S. as morally corrupt and racially prejudiced.

Philippines 1994–1995

During late 1994 and early 1995, Mohammed was present in the Philippines, where he posed as a Saudi or Qatari trader specializing in plywood, adopting the pseudonyms "Abdul Majid" and "Salem Ali."

Qatar, avoiding arrest

In early 1996, to evade capture by U.S. authorities, Mohammed escaped from Qatar and relocated to Afghanistan, where he reestablished connections with Rasul Sayyaf. Throughout his flight, he received protection from Sheikh Abdullah Al Thani, who was then serving as Qatar’s Minister of Religious Affairs.

Operation Bojinka

Mohammed traveled to the Philippines in 1994 to collaborate with his nephew, Ramzi Yousef, on the Bojinka plot—a scheme based in Manila aimed at destroying twelve commercial aircraft operating between the United States, East Asia, and Southeast Asia. According to the 9/11 Commission Report, this marked Mohammed’s initial engagement in orchestrating a terrorist attack.

In December 1994, Ramzi Yousef conducted a bomb test on Philippine Airlines Flight 434 using approximately ten percent of the intended explosives. This attack resulted in the death of a Japanese passenger on a flight from the Philippines to Japan. Until the plot’s discovery on January 6, 1995, Mohammed collaborated closely with Yousef. The latter was apprehended on February 7 of that year.

Mohammed was formally charged in January 1996 by the United States District Court for the Southern District of New York for his suspected involvement in Operation Bojinka and was subsequently placed on the FBI’s list of 22 Most Wanted Terrorists on October 10, 2001.

Relationship with Osama bin Laden

By the time authorities uncovered the Bojinka plot, Mohammed had returned to Qatar, where he was employed as a project engineer at the Ministry of Electricity and Water. In 1995, he traveled extensively—to Sudan, Yemen, Malaysia, and Brazil—to establish contacts within the international jihadist network; however, no direct evidence links him to attacks in these locations. While in Sudan, he sought an audience with Osama bin Laden, who was then residing there under the protection of Sudanese leader Hassan al-Turabi. Following a U.S. request for his arrest in January 1996, Mohammed fled to Afghanistan where he renewed associations with Abdul Rasul Sayyaf and later developed a collaborative relationship with Bin Laden.

During this time frame, Bin Laden and his associates shifted their operations to Afghanistan. Bin Laden’s operations chief, Mohammed Atef (Abu Hafs al-Masri), organized a meeting in 1996 at Tora Bora where Mohammed proposed a plan that eventually became the foundation for the 2001 coordinated hijackings. Although Bin Laden urged Mohammed to formally join al-Qaeda earlier, he declined until after the 1998 U.S. embassy bombings in Nairobi and Dar es Salaam, officially affiliating himself with al-Qaeda by early 1999.

In 1997, Mohammed relocated his family from Iran to Karachi, Pakistan. That same year, he made an unsuccessful attempt to join mujahideen leader Ibn al-Khattab in Chechnya, a region of strategic interest. After failing to reach Chechnya, Mohammed returned to Afghanistan and accepted Bin Laden’s invitation to move to Kandahar, formally becoming part of al-Qaeda. He ultimately assumed leadership of al-Qaeda’s media committee.

Planning the September 11 Attacks

Mohammed initially suggested hijacking multiple planes targeting both the East and West coasts of the United States, an evolution of the earlier Bojinka plot. Bin Laden dismissed some of Mohammed’s proposed targets, including Los Angeles' U.S. Bank Tower, opting instead for a more streamlined attack plan.

By late 1998 or early 1999, Bin Laden authorized Mohammed to coordinate the operation. Early meetings in 1999 involved Mohammed, Bin Laden, and military commander Mohammed Atef. Bin Laden provided leadership and funding, handpicking operatives such as lead hijacker Mohamed Atta. Mohammed handled operational logistics like target selection and travel arrangements, while Atef oversaw the hijackers’ tactical execution.

Following Atta’s designation as mission commander, he met with Bin Laden to confirm the targets: the World Trade Center symbolizing U.S. economic dominance; the Pentagon representing military power; and the U.S. Capitol, viewed as a policy hub supporting Israel. The White House was also considered for its political symbolism. In cases where pilots could not reach their objectives, they were instructed to deliberately crash.

Philip Zelikow testified that Bin Laden wished to accelerate the attack timeline as retaliation for U.S. support of Israel, suggesting that simply downing planes might be sufficient. In contrast, Mohammed emphasized rigorous pilot training and larger hijacking teams to ensure success.

In a 2002 interview with Yosri Fouda on Al Jazeera Arabic, Mohammed acknowledged collaborating with Ramzi bin al-Shibh in planning the "Holy Tuesday operation," the codename for 9/11. However, he denied leading al-Qaeda's military committee.

In a subsequent April 2002 interview with Fouda, both Mohammed and al-Shibh disclosed that they initially contemplated attacking U.S. nuclear facilities but ultimately decided against including these targets in the operation.

Murder of Daniel Pearl

Intelligence analyst Rohan Gunaratna stated in a CNN interview that Daniel Pearl was investigating al-Qaeda’s network in Karachi when he was killed under orders from Khalid Sheikh Mohammed (KSM). On October 12, 2006, Time magazine reported that KSM confessed during CIA interrogation to personally executing Pearl. The Pentagon confirmed on March 15, 2007, that Mohammed admitted beheading Pearl in Karachi, declaring, "I decapitated with my blessed right hand the head of the American Jew, Daniel Pearl." These confessions were obtained under coercive interrogation methods alongside admissions of other offenses.

A 2011 investigation by Georgetown University revealed that the FBI used vein pattern matching to identify a distinctive bulging vein on the killer’s hand in the video as likely belonging to Mohammed. Concerned about the admissibility of torture-obtained confessions, federal authorities relied on this forensic evidence to bolster their case.

Capture, Interrogation, and Torture

On September 11, 2002, Pakistan’s Inter-Services Intelligence (ISI) announced they had killed or captured Sheikh Mohammed during a raid in Karachi that led to bin al-Shibh's arrest; this claim was later disproven.

Mohammed was apprehended in Rawalpindi, Pakistan on March 1, 2003 by ISI agents—possibly assisted by CIA Special Activities Division operatives and U.S. Diplomatic Security officers—and has remained in U.S. custody since.

Initially detained at the CIA’s Salt Pit facility in Afghanistan, Mohammed was subjected to “enhanced interrogation techniques” such as slapping, stress positions, sleep deprivation, water dousing, and repeated rectal hydration without medical justification.

In 2003 he was transferred to secret CIA prisons (black sites) in Poland—where he endured waterboarding at least 183 times—and later moved to Romania.

In September 2006, U.S. authorities relocated Mohammed from CIA custody to Guantanamo Bay military detention center. Organizations like the Red Cross and Human Rights Watch classify these harsh interrogation methods—including waterboarding—as torture. During detention he experienced prolonged sleep deprivation exceeding seven days and was frequently compelled to stand for extended periods.

Mohammed initially refused cooperation without legal representation and reported being kept naked for over a month while isolated and interrogated by numerous female interrogators.

A CIA document reveals that on July 13, 2004, members of the House Intelligence Committee Jane Harman and Porter Goss received briefings on Mohammed’s interrogation status. The CIA sought renewed authorization from NSC Principals to continue enhanced interrogation procedures.

In October 2004 Human Rights Watch reported that Mohammed and ten others had been transferred to a semi-secret prison in Jordan where torture might have occurred under CIA oversight; officials denied these allegations.

In October 2006 Mohammed recounted his mistreatment—including waterboarding—to the International Committee of the Red Cross (ICRC). He admitted providing false information to end his suffering. During his first month at a third detention facility he stated he underwent five waterboarding sessions; officials clarified that the figure of 183 referred to individual applications within those sessions.

By March 2007—after four years in custody including six months at Guantanamo Bay—Mohammed confessed during a Combatant Status Review Tribunal that he masterminded the September 11 attacks along with other plots such as Richard Reid’s shoe bombing attempt, the 2002 Bali nightclub bombing, and the 1993 World Trade Center bombing. He declared: "I was responsible for the 9/11 operation from A to Z."

A confiscated hard drive contained extensive data on September 11 hijackers including flight records, photographs, pilot license payments for Mohamed Atta, chat logs, letters from Osama bin Laden, financial support details for al-Qaeda families, threats against UAE officials, operational manuals for al-Qaeda cells, and casualty lists. Mohammed attributed this device to co-arrestee Mustafa Ahmad al-Hawsawi.

On February 5, 2008 CIA Director Michael Hayden confirmed waterboarding was employed on Mohammed. By June 2008 reports placed him at a Polish black site near Szymany Airport where waterboarding occurred prior to his cooperation.

In 2009 Mohammed published The Islamic Response to the Government's Nine Accusations, explaining his motives.

Leaked Guantanamo files released by The Daily Telegraph in April 2011 revealed that Mohammed warned coalition forces that if Osama bin Laden were captured or killed, an al-Qaeda sleeper cell would unleash a “weapon of mass destruction” in Europe—a “nuclear hellstorm.” This highlighted ongoing threats linked to his network despite his incarceration.

Allegations of Abuse Against His Children by Interrogators

Ali Khan, the father of Majid Khan, one of the fourteen designated "high-value detainees," submitted an affidavit on 16 April 2006 accusing interrogators of mistreating the children of Khalid Sheikh Mohammed, who were six and eight years old at the time. The affidavit included testimony from Mohammed Khan, Ali Khan's son, who recounted how Pakistani guards deprived the boys of food and water and used insects to intimidate them in order to extract information about their father's location.

Detainment at Guantanamo and Combatant Status Review Tribunal Appearance

On 6 September 2006, President George W. Bush publicly acknowledged that the CIA had held "high-value detainees" in undisclosed detention facilities and announced their transfer—comprising fourteen senior captives including Khalid Sheikh Mohammed—to military custody at the Guantanamo Bay detention camp. These individuals were slated to face military commission charges.

During a speech on 29 September 2006, President Bush credited intelligence gathered through interrogations with thwarting several terrorist operations targeting locations such as the United States, Djibouti, Karachi, and London.

In March 2007, Mohammed appeared before a closed session at Guantanamo where he confessed involvement in significant terrorist incidents including the 1993 World Trade Center bombing, the Bali nightclub bombings, Richard Reid's failed shoe bombing attempt, planned attacks in London, the murder of Daniel Pearl, and assassination plots against Pope John Paul II, Pervez Musharraf, and Bill Clinton.

He admitted to the human toll caused by conflict but contextualized it within shared religious prohibitions against killing.

According to a BBC News report dated 15 March 2007, transcripts from his testimony were redacted to omit sensitive details. Although Mohammed claimed his statements were not coerced, human rights organizations have alleged torture. CIA officials acknowledged that he underwent extensive waterboarding. Legal authorities caution that such treatment risks compromising the reliability of his confessions. Forensic psychiatrist Michael Welner proposed that familial concerns rather than mistreatment primarily motivated Mohammed’s cooperation.

A CIA representative warned that many of Mohammed’s declarations were deceptive or exaggerated with the intent to mislead interrogators. Former FBI agent Mike Rogers pointed out that Mohammed’s admitted role in the Bali bombing might have been limited to logistical assistance. Similarly, despite claims of responsibility for the 1993 World Trade Center attack, evidence indicates a more peripheral involvement. Welner noted that providing some factual information allowed Mohammed to introduce falsehoods strategically.

Ex-FBI agent Ali Soufan stressed that torture frequently results in unreliable confessions as subjects may say anything to end suffering. This view aligns with guidance from the U.S. Army Training Manual which cautions that coercion can produce inaccurate statements.

Assertions by the Bush administration that waterboarding Mohammed led to critical intelligence breakthroughs—such as preventing a 2002 plot against Los Angeles’ U.S. Bank Tower or locating Osama bin Laden—have been disproved. At that time, Mohammed was actively evading capture in Pakistan. Claims made by former Attorney General Michael Mukasey and CIA official Jose Rodriguez regarding intelligence gains from his torture have also been challenged. Senator John McCain stated that enhanced interrogation techniques applied to Mohammed generated false leads rather than vital information about bin Laden or his courier.

Catalog of admissions

Mohammed has confessed to at least 31 distinct plots, encompassing significant terrorist operations with profound business and geopolitical consequences:

The February 1993 explosion at New York City's World Trade Center
The September 11 attacks involving hijacked commercial airplanes targeting the World Trade Center and the Pentagon
An unsuccessful attempt known as the "shoe bomber" plot
The October 2002 assault in Kuwait
The beheading of Wall Street Journal journalist Daniel Pearl
The 2002 Bali bombings, including the bombings of Pady's and Sari's clubs in Bali, Indonesia
A planned "second wave" of assaults on prominent U.S. landmarks following 9/11, aimed at the Library Tower in Los Angeles, the Willis Tower in Chicago, the Empire State Building in New York City, and a reported Plaza Bank Building in Seattle (likely Safeco Plaza or Columbia Center)
Schemes to target oil tankers and U.S. naval vessels in the Straits of Hormuz, Straits of Gibraltar, and Singapore
A conspiracy to destroy the Panama Canal
Assassination plans against former U.S. President Jimmy Carter and Pakistani President Pervez Musharraf
Plots involving fuel truck bombings aimed at suspension bridges in New York City and the Sears Tower in Chicago
Planned attacks on London sites such as London Heathrow Airport, Canary Wharf, and Big Ben
A proposed assault on several nightclubs located in Thailand
A conspiracy targeting the New York Stock Exchange along with other key U.S. financial institutions
Plans to demolish structures in Eilat, Israel, and U.S. embassies situated in Indonesia, Australia, and Japan
Plots against Israeli diplomatic missions in India, Azerbaijan, the Philippines, and Australia
Funding an attack on an Israeli El-Al flight departing from Bangkok
Dispatching operatives into Israel to conduct reconnaissance on strategic targets
The November 2002 suicide bombing at a hotel in Mombasa, Kenya, coupled with a failed attempt to down an Israeli passenger plane leaving Mombasa Airport
Schemes targeting U.S. interests in South Korea and Turkey, including financial backing for assaults on U.S., British, and Jewish entities
Surveillance activities focused on U.S. nuclear power facilities for possible attacks
A plot directed at NATO's European headquarters
The 1995 "Bojinka plot" involving plans to bomb twelve American passenger airplanes
An assassination attempt against then-U.S. President Bill Clinton during a mid-1990s visit to the Philippines
Shared involvement in a conspiracy to assassinate Pope John Paul II
An attempted attack on a U.S. oil company in Sumatra owned by former U.S. Secretary of State Henry Kissinger

Following Mohammed’s relocation to Guantanamo Bay, interrogators from the FBI and military employed lawful techniques to secure confessions akin to those previously obtained by the CIA concerning the 9/11 conspiracy. By 2008, sufficient evidence had been amassed by the Bush administration to bring capital murder charges against Mohammed and others.

On August 9, 2007, the United States Department of Defense designated all fourteen "high-value detainees" transferred from CIA secret prisons as "enemy combatants." Although prior court decisions had restricted military commissions to "illegal enemy combatants," this designation was waived by the Department of Defense, permitting all fourteen detainees to be prosecuted before Guantanamo military tribunals.

Use of Confession in Defense of Sheikh Omar

On 19 March 2007, the defense attorneys for Ahmed Omar Saeed Sheikh introduced Mohammed's confession as part of their legal strategy. Known also as Sheikh Omar, Ahmed Omar Saeed Sheikh had been condemned to death by a Pakistani tribunal for the killing of Daniel Pearl. His legal team intended to incorporate Mohammed's admission in an appeal, conceding Omar's participation but asserting that Mohammed was the principal perpetrator.

Prosecution Proceedings in France

In 2009, French authorities opted to prosecute Khalid Sheikh Mohammed in absentia on terrorism accusations linked to the 2002 Ghriba synagogue bombing on Djerba, Tunisia, which resulted in 21 fatalities, including German and French citizens. He was slated to be tried alongside German national Christian Ganczarski and Tunisian Walid Nawar. Subsequently, French judges decided to separate Mohammed’s case for a distinct trial.

Trial Concerning Involvement in the September 11 Attacks

On 11 February 2008, the United States Department of Defense formally charged Mohammed and four other defendants under the provisions of the Military Commissions Act of 2006 for their alleged roles in the September 11 attacks. The indictments encompassed charges such as the murder of nearly 3,000 individuals, acts of terrorism, hijacking aircraft, assaulting civilian targets, along with numerous related offenses totaling 169 overt acts.

The prosecution is pursuing the death penalty, which necessitates unanimous consent from the military commission judges. Critics from human rights organizations and defense counsel have condemned the military commissions for insufficient procedural safeguards, advocating instead for trials in federal courts or court-martials conducted under the Geneva Conventions. Regardless of the judicial forum, Mohammed faces potential capital punishment.

The legal process has experienced delays; an initial trial date was tentatively set for 11 January 2021 but was deferred due to the COVID-19 pandemic. Proceedings resumed on 7 September 2021. On 31 July 2024, a plea agreement was reached wherein Mohammed pled guilty and avoided the death sentence in exchange for life imprisonment; however, Defense Secretary Lloyd Austin revoked this agreement two days afterward.

Judicial Decisions Impacting Him

In Boumediene v. Bush (2008), the United States Supreme Court upheld detainees’ entitlement to seek relief through US federal courts by filing habeas corpus petitions challenging their detention conditions. The Court found deficiencies in both the Detainee Treatment Act of 2005 and the Military Commissions Act of 2006. Consequently, Congress enacted a revised version known as the Military Commissions Act in 2009 to remedy these issues.

On 26 July 2019, Mohammed submitted correspondence indicating his readiness to cooperate with victims and their families involved in lawsuits against Saudi Arabia related to 9/11, reportedly requesting that his death sentence be lifted in return for his assistance.

On 16 August 2023, officials from the Pentagon and FBI notified families of victims that none of those accused as organizers of the September 11 attacks would be subjected to capital punishment amid ongoing plea bargain discussions.

Publication of New Photographs

On 9 September 2009, new images depicting Khalid Sheikh Mohammed and Ammar al Baluchi were released online and received extensive coverage by US and global media outlets. Typically, stringent regulations restrict public release of detainees’ facial images; journalists are permitted to observe high-profile detainees like Mohammed only during court sessions where photography is prohibited. These particular photographs were captured in July under an arrangement permitting the International Committee of the Red Cross to take pictures and forward them to detainees’ relatives.

In November 2014, a Turkish company sparked controversy by utilizing a photo showing a disheveled Mohammed in promotional material for an over-the-counter hair removal product.

Manifesto

In January 2014, the US government declassified and published a 36-page document authored by Khalid Sheikh Mohammed (KSM), titled a "nonviolence manifesto." Known as "Khalid Sheikh Mohammad's Statement to the Crusaders of the Military Commissions in Guantanamo," it is divided into three segments; however, only the initial part, which discusses "the path to happiness," was made available. This text is directed toward his captors and seeks to persuade a broader audience to embrace Islam. The manifesto cites eight books, including three authored by Western writers, with references dated October 31, 2013.

Khalid Sheikh Mohammed and Sulaiman Abu Ghaith

Khalid Sheikh Mohammed provided testimony during the legal proceedings involving alleged al-Qaeda operatives Zacarias Moussaoui and Salim Hamdan. As reported by Los Angeles Times journalist Richard Serrano, summaries from Mohammed’s interrogations had an impact on judicial decisions: Moussaoui avoided capital punishment in 2006, and Hamdan was released from Guantanamo Bay in 2008.

Attorney Stanley Cohen, representing Sulaiman Abu Ghaith, sought to interview Mohammed, considering him "the most qualified person alive" to aid the defense. Mohammed consented to an interview only if no government officials were present. Instead of a direct meeting, he provided a 14-page written reply addressing 451 questions.

Within this statement, Mohammed portrayed Abu Ghaith as a "devout man" and "captivating orator," denying any military involvement or training within al-Qaeda. He criticized Western foreign policies for supporting the Mujahideen during the Soviet-Afghan conflict but later branding them terrorists. Mohammed also asserted that the Taliban’s strict Islamic governance brought stability to Afghanistan throughout the 1990s. U.S. District Judge Lewis A. Kaplan deemed Mohammed's statement and testimony irrelevant and inadmissible for Abu Ghaith’s trial.

Personal life

Mohammed is proficient in Balochi, Urdu, Arabic, and English. At the time of his arrest in 2002, he had two sons aged seven and nine.
