A federal appeals court on Friday threw out a deal that would have allowed the accused mastermind of the Sept. 11, 2001, attacks to plead guilty in exchange for life imprisonment.
The deal, negotiated over two years and approved one year ago by military prosecutors and the Pentagon’s senior official for Guantanamo Bay, Cuba, stipulated life sentences without parole for Khalid Sheikh Mohammed, a Pakistani national who was a leader of terrorist group al-Qaeda, and two co-defendants.
