9/11 Mastermind Khalid Sheikh Mohammed Set for Military Trial in June 2028

After two decades of legal deadlock and numerous setbacks, a U.S. Air Force judge has ordered the trial of Khalid Sheikh Mohammed, accused mastermind of the September 11, 2001 attacks, to commence on June 5, 2028 before a military tribunal at Guantanamo Bay, Cuba. The decision by Judge Michael Schrama comes after years of legal battles and political controversy surrounding the case.

The trial will involve four defendants: Khalid Sheikh Mohammed, Walid Muhammad Salih Mubarak bin 'Atash, Mustafa Ahmed Adam al Hawsawi, and Ali Abdul Aziz Ali. All are held at the Guantanamo Bay detention facility established by President George W. Bush in 2002 to house suspected terrorists following the 9/11 attacks.

In 2024, a plea deal was proposed that would have allowed Mohammed and two co-defendants to plead guilty while avoiding the death penalty. However, this agreement faced significant opposition from Republican lawmakers and was ultimately revoked by then-Defense Secretary Lloyd Austin in August of that year. The U.S. Court of Appeals later overturned the military judge's decision supporting the plea deal, further delaying the proceedings.

The trial is expected to begin with the selection of a jury panel consisting solely of service members who will adhere to the rules of military justice throughout the process. Opening statements will follow 30 days after the jury is seated, followed by the presentation of evidence from both sides. The prosecution's case will be presented first, and once concluded, the defense will have an opportunity to present its own principal evidence.

Schrama's order sets a detailed timeline for the trial, including opportunities for motions and rebuttals from both sides before entering the sentencing phase. However, the judge rejected earlier proposals to start the trial in January 2027 due to insufficient time needed to resolve pretrial evidentiary and compliance issues.

Khalid Sheikh Mohammed remains one of the most notorious inmates at Guantanamo Bay. He is accused of orchestrating the hijacking of four passenger jets on September 11, 2001, which were flown into the World Trade Center in New York City and the Pentagon, resulting in nearly 3,000 deaths.

The upcoming trial marks a significant milestone in the legal proceedings against those responsible for one of the most devastating terrorist attacks in U.S. history, bringing renewed attention to the ongoing legacy of the September 11 attacks and the challenges faced by the military justice system in handling such high-profile cases.
