I found this at Dohiyi Mir:
An Iraqi humanitarian organization is reporting that 128,000 Iraqis have been killed since the U.S. invasion began in March 2003...[which] includes everyone who has been killed since that time, adding that 55 percent of those killed have been women and children aged 12 and under.
'Iraqiyun obtained data from relatives and families of the deceased, as well as from Iraqi hospitals in all the country's provinces. The 128,000 figure only includes those whose relatives have been informed of their deaths and does not include those were abducted, assassinated or simply disappeared.
'Iraqiyun's figures conflict with the Iraqi Body Count public database compiled by Geneva-based Graduate Institute of International Studies. According to the Graduate Institute of International Studies' database, 39,000 Iraqis have been killed as a direct result of combat or armed violence since March 2003.
For those of you keeping score at home, 128k is ~43 times how many Americans died on September 11th, 2001. Proportionally, it's equivalent to ~466 September 11ths.
