The Washington Post reports a military judge ruled Thursday that one of the five defendants being tried at Guantanamo Bay, Cuba, for their alleged roles in the Sept. 11, 2001, attacks be severed from the proceeding. The decision delivers another in a series of delays to the government’s effort to prosecute Ramzi Binalshibh, a Yemeni described as a key figure in the plot who acted as a liaison between the hijackers and al-Qaeda’s leadership in Afghanistan. But the order could accelerate pre-trial proceedings for the four others, including the self-proclaimed mastermind of the attacks, Khalid Sheik Mohammed. Army Col. James L. Pohl said the court needs to resolve whether Binalshibh has the mental capacity to participate in a trial and whether he needs another lawyer because of a potential conflict of interest after the FBI questioned members of his defense team. These issues “are not expected to be completed in the near term,” Pohl said in his order.
