Khalid Sheikh Mohammed, the alleged mastermind of the September 11 attacks, is set to stand trial before a US military commission at Guantanamo Bay on June 5, 2028, alongside three co-defendants.
The trial date was set by a military judge after prosecutors had sought to begin proceedings in January 2027. The court ruled that more time was needed to resolve outstanding pretrial and evidentiary issues in a case that has faced years of legal delays.
Mohammed, once regarded as a senior Al-Qaeda operative and close associate of Osama bin Laden, was captured in Pakistan in March 2003.
He spent three years in secret CIA detention facilities before being transferred to the US military prison at Guantanamo Bay, Cuba, in 2006, where he has remained ever since.
The planned 2028 trial marks the latest attempt to bring the long-running case to trial, more than two decades after the attacks that killed nearly 3,000 people. However, the proceedings could still face further delays if key pretrial deadlines are not met.
