WASHINGTON, Aug. 16 (AP) — Ninety-nine soldiers killed themselves last year, the highest suicide rate in the Army in 26 years of record-keeping, a new report says.

Nearly a third of the soldiers committed suicide while in Iraq or Afghanistan, according to a report released Thursday, which said 27 deaths were in Iraq and 3 in Afghanistan.

The report said that the 99 confirmed suicides by active-duty soldiers compared with 87 in 2005 and that it was the highest raw number since 102 suicides were reported in 1991, the year of the Persian Gulf War.

Investigations are pending on two other deaths.

Officials reported 948 suicide attempts, but there were no comparisons for previous years.
