BAGHDAD, Iraq (CNN) -- The year's second-highest monthly total of bodies arrived at Baghdad's morgue in August, Iraqi authorities said, but the figures do not include people killed by bombs or other mass attacks.

About 1,500 bodies were delivered to Baghdad's morgue last month, according to figures provided by an Iraqi Health Ministry official on condition of anonymity. The figure is second only to July's toll of 1,850 bodies.

Of the bodies taken to the morgue last month, 90 percent had been shot, the official said. The other 10 percent were killed by other means, including torture, beheading and stabbing, the official said.

The official noted that the morgue figures did not include most bombing victims, as that number was calculated separately.

On Monday, the U.S. Command acknowledged that its report of a dramatic drop in murders in Baghdad last month did not include people killed by bombs, mortars, rockets or other mass attacks, The Associated Press reported. The count only included victims of drive-by shootings and those killed by torture and execution.
