WASHINGTON - A US Army psychiatrist declared some suicide bombings acceptable and offered money to a militant Muslim cleric in emails months before he was accused of killing 13 people at Fort Hood, Texas, according to copies of the emails released on Thursday.

The emails became public for the first time as part of a report assessing what the FBI knew about Major Nidal Hasan and whether the agency could have prevented his 2009 shooting spree.

Hasan, 41, is scheduled to stand trial in a military court-martial on Aug. 20 for the shooting spree, which also wounded more than 30. He faces the death penalty if convicted.

The new report by former FBI Director William Webster faulted the FBI for not being more alarmed that Hasan, while in the military, was in contact with Anwar al-Awlaki, a US-born Muslim cleric who was being tracked by US intelligence because of his extreme views.
