GUANTANAMO BAY NAVAL BASE, Cuba (AP) — Lawyers for Guantanamo prisoners charged in the Sept. 11 attack say the FBI has questioned more support staff on their legal teams, a development that may prompt a new detour in an already snarled case as the war crimes tribunal reconvened Monday at this U.S. base.

The trial by military commission of the five prisoners was derailed in April when the attorney for one defendant revealed that a member of his support staff was questioned at home by the FBI and asked to provide information on others who work for the defense.
