Trial for 9/11 mastermind Khalid Sheikh Mohammed set for June 2028

A U.S. military court has scheduled the trial of Khalid Sheikh Mohammed, the alleged mastermind behind the September 11, 2001, terrorist attacks, for June 5, 2028. Mohammed, a former high-ranking Al-Qaeda official, was captured in Pakistan in March 2003 and subsequently held at CIA secret sites in Poland, where he was subjected to interrogation and torture. He has been detained at the Guantanamo Bay military prison since September 2006.

Legal proceedings regarding his case have faced significant volatility. In July 2025, a U.S. appeals court invalidated a plea agreement that would have allowed Mohammed and two co-defendants to avoid the death penalty in exchange for guilty pleas. The current trial date remains subject to potential postponement due to unresolved procedural issues, specifically concerning the admissibility of various pieces of evidence. As the proceedings move forward, the military court continues to grapple with these foundational legal challenges that have prolonged the detention of the accused for two decades.
