US Supreme Court denies 9/11 mastermind plea deal, death penalty remains

The Supreme Court declined to reinstate plea agreements for Khalid Sheikh Mohammed and two co-defendants, keeping the death penalty possible ahead of a June 2028 military trial. The ruling follows a lower court's rejection of the deals, which had been negotiated to avoid capital punishment. This decision prolongs a 25-year legal saga and maintains the possibility of a death sentence for the accused plotters.
