GUANTANAMO BAY NAVAL BASE, Cuba — A pretrial hearing in the Sept. 11 war crimes case started Thursday with an angry outburst from one of the defendants complaining about searches of his cell by guards at the Guantanamo Bay prison.

Walid bin Attash stood up to complain about the searches and sought to address the court but was repeatedly interrupted and told to sit down by the military judge, Army Colonel James Pohl.
