Waalid bin Attaash

Walid Muhammad Salih bin Mubarak bin Attash is a Yemeni prisoner held at the United States' Guantanamo Bay detention camp under terrorism-related charges and is suspected of playing a key role in the early stages of the 9/11 attacks. The Office of the Director of National Intelligence has described him as a "scion of a terrorist family". American prosecutors at the Guantanamo military commissions allege that he helped in the preparation of the 1998 East Africa Embassy bombings and the 2000 USS Cole bombing and acted as a bodyguard to Osama bin Laden, gaining himself the reputation of an "errand boy". He is formally charged with selecting and helping to train several of the hijackers of the September 11 attacks. On 31 July 2024, Attash agreed to plead guilty to avoid the death penalty. His plea deal was revoked by Secretary of Defense Lloyd Austin two days later.
