Five men accused of orchestrating the Sept. 11 attacks, including the self-proclaimed mastermind, are headed back to a military tribunal at Guantanamo Bay Saturday, more than three years after President Barack Obama put the case on hold in a failed effort to move the proceedings to a civilian court and close the prison at the US base in Cuba. This time the defendants may put up a fight. Khalid Sheikh Mohammed, who told military authorities that he was responsible for the planning of the terror assault “from A to Z,” previously mocked the tribunal and said he would welcome the death penalty. His co-defendant, Ramzi Binalshibh, told the court that he was proud of the attacks. But Jim Harrington, the civilian lawyer for Binashibh, said the defendants are expected to fight the charges against them, which include murder and terrorism and carry a potential death penalty. “He has no intention of pleading guilty,” Harrington said. “I don't think anyone is going to plead guilty.” Harrington declined to say what would be the basis of his defense and lawyers for Mohammed did not respond to messages seeking comment. The men never entered formal pleas in previous hearings, but Mohammed told the court that he would confess to planning the attacks and hoped to be a “martyr.”
