The alleged mastermind of the 9/11 attacks will stand trial in June 2028

Khalid Sheikh Mohammed, accused of planning and organizing the September 11, 2001 attacks, will stand trial in June 2028 before a U.S. military tribunal. The date was set by a judge, nearly 3 years after the attacks that killed almost 000 people in the United States.

Nicknamed "KSM," the Pakistani, raised in Kuwait, is considered one of Al-Qaeda's top lieutenants. He is believed to have suggested to Osama bin Laden as early as 1996 that they use airliners as weapons. Captured in Pakistan in March 2003, he was subsequently held in secret CIA prisons, where he was subjected to torture, before being transferred to Guantanamo in September 2006.

The agreement that likely spared him the death penalty was cancelled.

Khalid Sheikh Mohammed was initially scheduled to plead guilty along with his two co-defendants, Walid Bin Attash and Mustafa Al-Hawsawi, as part of a plea agreement that would likely have allowed them to avoid the death penalty. However, this negotiated procedure was overturned in July 2025 by a US appeals court.

The three men will face charges of terrorism and the murder of nearly 3,000 people. The opening of this landmark trial comes after years of legal battles, particularly concerning interrogations under torture and the admissibility of evidence gathered by US authorities.
