Khalid Sheikh Mohammed
Pakistani militant who was a member of al-Qaeda

Khalid Sheikh Mohammed (born 14 April 1965; Urdu: خالد شیخ محمد; sometimes also spelled Shaykh; and known by at least 50 pseudonyms including his initials KSM) is a Kuwaiti-born Pakistani militant, and the former head of propaganda for al-Qaeda. As of 2026, he is held by the United States at the Guantanamo Bay detention camp under terrorism-related charges. He was named as "the principal architect of the 9/11 attacks" in the 2004 9/11 Commission Report.
Mohammed was a member of Osama bin Laden's militant organization al-Qaeda, leading al-Qaeda's propaganda operations from around 1999 until late 2001. Mohammed was captured on 1 March 2003, in the Pakistani city of Rawalpindi by a combined operation of the U.S. Central Intelligence Agency (CIA) and Pakistan's Inter-Services Intelligence (ISI). Immediately after his capture, Mohammed was taken to secret CIA prison sites in Afghanistan, then Poland, where he was interrogated by U.S. operatives. By December 2006, he had been transferred to military custody at Guantanamo Bay detention camp.
Mohammed is widely regarded as the chief planner of the September 11 attacks. The United States government has alleged that he further participated in planning Richard Reid's shoe bombing attempt to attack an airliner; the 2002 Bali bombings in Indonesia; the 1993 World Trade Center bombing; the murder of Daniel Pearl and various foiled attacks as well as numerous other crimes. These claims have been criticised by others, such as military prosecutor Moe Davis and journalist Andrew Brown, as inadmissible due to being obtained through torture.

Why this record matters

The linked authority identifier is Q319068. VIAF identifies the subject as 98063170. The Library of Congress control number is nb2003006574. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
