Reuters: A U.S. military court on Wednesday tried to assess whether government agents interfered with the trial of five men charged with the Sept. 11, 2001, attacks on the United States by spying on defenses attorneys and their clients.

The judge halted the pre-trial hearing at the Guantanamo Bay, Cuba, military prison on Monday after one of the defendants said his interpreter had worked at a secret CIA prison.

When the hearing resumed on Wednesday, defenses attorneys contended the Federal Bureau of Investigation and Central Intelligence Agency had planted Arabic interpreters on the defenses team, bugged conversations between the attorneys and their clients and questioned their support staff.
