About the only halfway credible tally of military-action-related civilian deaths in Iraq is
IraqBodyCount , a website operated by an anti-war group, which since the beginning of hostillities has maintained a running update based on independently multiply verifiable civilian deaths due to military activity. Some discrepancies exist, which they accommodate by listing "minimum-maximum" figures. The current figure is between 14, 378 and 16,514.
It should be noted they include in their running total deaths caused by insurgent activity - car bombs, assassinations, etc. - as well as by Coalition activity, and it should be noted too that Iraqi-on-Iraqi violence accounts for exponentially more Iraqi deaths than does Coalition activity.
The detail database available there does disclose that, thouh the running total min/max tally makes no such distinction. Final caveat; digging a bitdeeper into their database reveals that some 3029 war-dead civilians have been identified by name. Draw your own conclusion.
Current DoD-released casualty count in Fallujah is a bit more than 30 Own Force, the preponderance of which are American, and 1800 to 2000 inurgents killed, approximately 500 in custody. Several hundred of the killrd and captured have been positively identified as foreign nationals, Syrians, Egyptians, Jordanians, Iranians, and Somalis, mostly, but Chechens, Afghanis, and others have been confirmed also.
