Several former workers at a Marine Corps brig in Quantico, Va., say that an Army private charged with providing classified information to the secret-spilling WikiLeaks website was so withdrawn that they considered him at risk of hurting himself.

Testimony by ex-staff members continues Sunday at a pretrial hearing for Pfc. Bradley Manning.

The hearing is to determine whether the highly restrictive conditions he experienced for nine months were justified. The defense claims the restrictions were so punishing that the case should be dismissed.

Two psychiatrists have testified that the brig commander kept Manning tightly confined despite their recommendations to ease them.

Manning, 24, is charged with 22 offenses, including aiding the enemy. He could get life in prison.

The hearing, in its sixth day, will recess Sunday and resume Wednesday.
