A new study from an Iraqi humanitarian organization is estimating that 128,000 Iraqis have been killed since the U.S. invaded in March 2003. The group — Iraqiyun — estimates that 55 percent of those killed have been women and children aged twelve and under. Meanwhile the Geneva-based Graduate Institute of International Studies has also attempted to estimate the number of Iraqis killed. The organization recently estimated that 39,000 Iraqis have been killed as a direct result of combat or armed violence since the war began.
