The U.S. Agency for International Development has completed a study on the mass graves during Saddam Hussein's regime in Iraq. It's grim, writes Andrew Natsios, who runs the agency:

Rows of white bundles containing bones filled room after room. Families filed by, searching for signs of those who had disappeared, some stolen during the night, others taken in daylight. Even small children were not spared the butchery.

So far, 270 mass graves have been found which contained the remains of 400,000 Iraqis.
