Civilian and ‘friendly fire’ casualties

Airwars maintains an extensive all-source database of known allegations in which civilians and friendly forces have been reported killed by the Coalition or Russia in Iraq and Syria. Our individual case studies include photographs, videos, names of the dead, and links to all known sources. These reports represent our best current understanding of events and are updated as new information becomes available.

Summary findings on Coalition air and artillery strikes: August 8th 2014 to October 31st 2017

To October 31st 2017 an overall total of between 16,592 and 24,640 civilian non-combatant fatalities had been locally alleged from 2,341 separate reported Coalition incidents, in both Iraq and Syria. Of these, Airwars presently estimates that a minimum of 5,961 to 9,054 civilians are likely to have died in Coalition actions. However, some caution is needed given the significant challenges of casualty verification at present.

See our separate tracking of alleged Russian events here

The Coalition has so far confirmed 186 of 2,341 claimed incidents as causing 706 civilian fatalities. In addition 80 further civilian deaths have been confirmed in unidentified incidents. Airwars estimates that between 961 and 1,528 or more non-combatants in fact died overall in these confirmed incidents. (In order to avoid double counting these 80 unknown Coalition fatalities, we have estimated that half of them may already have been counted elsewhere in our data. This matches the proportion of already admitted Coalition cases which were publicly reported at the time.)

In addition to these confirmed events, it is our provisional view at Airwars that between 5,000 and 7,526 civilian non-combatants appear likely to have been killed in 945 further incidents where there is fair and uncontested public reporting of an event – and where Coalition strikes were confirmed in the near vicinity on that date. Some 179 of these likely incidents were in Iraq (1,504 to 2,227 reported deaths) and 766 events in Syria (with a reported fatality range of 3,487 to 5,288.)

At least 1,241 children and 739 women are reported to be among those killed in confirmed and likely events, along with 4,583 or more civilians reportedly injured. Airwars presently lists the names of 2,843 reported civilian fatality victims from confirmed and likely Coalition events.

Across both nations, 121 alleged civilian casualty incidents have so far in our view been discounted, ie are highly unlikely to have involved Coalition aircraft (698 to 1,096 claimed deaths). This categorisation is often a result of Coalition feedback on alleged incidents. An additional 382 to 528 civilians reportedly died in 64 events where the reporting appears fair, but where it remains unclear whether the Coalition carried out any attack in the vicinity on the date in question.

A further 2,151 to 2,521 claimed deaths are attributed to 402 alleged Coalition airstrikes which are presently weakly reported or single-sourced.

An additional 6,451 to 10,054 asserted fatalities resulted from 476 contested events (for example, claims that the Iraq Air Force or proxy ground actions might instead have been responsible.)

Some 132 further contested events (824 to 1,217 deaths) may have involved Russian aircraft in Syria. And 22 additional contested events (156 to 203 deaths) were attributed variously both to the Coalition and to Turkey.

The Coalition has additionally conceded four ‘friendly fire’ incidents. It has confirmed it likely killed Iraq Army forces at Fallujah on December 18th 2015, which the public record indicates killed 10 to 23 Iraqi troops. On September 17th 2016, between 15 and 65 Assad regime troops died in a Coalition action in Syria. On October 5th 2016, between 18 and 21 friendly Sunni tribal militia were killed in a Coalition strike near Qayyarah. And on April 11th 2017 the Coalition killed 18 SDF forces near Tabqah in Syria. Several hundred additional ‘friendly fire’ deaths of allied ground forces and non-friendly forces have been attributed to the Coalition from 56 more claimed incidents, with varying levels of credibility.

In its own latest monthly civilian casualty assessment – published on October 27th 2017 – the Coalition noted the following: “In the month of September, CJTF-OIR carried more than 344 open reports of possible civilian casualties from previous months and received 302 new reports resulting from Coalition strikes (artillery or air) in support of partner force operations to defeat ISIS in Iraq and Syria.  During this period, the Coalition completed the assessment of 127 reports: 105 were assessed to be non-credible, six were assessed to be duplicates of previous reports, and 16 were assessed to be credible, resulting in 51 unintentional civilian deaths. To date, based on information available, CJTF-OIR assesses at least 786 civilians have been unintentionally killed by Coalition strikes since the start of Operation Inherent Resolve. A total of 519 reports are still open and being assessed at the end of the month.

Airwars continues to improve its understanding of individual allegations – and our data and case reports include reference to the Coalition’s own assessments where known. Our data is also regularly adjusted to reflect those alleged cases where the alliance has demonstrated it was not responsible for non-combatant fatalities.

How we grade alleged incidents

Because of wide variations in the quality of casualty recording, Airwars uses a grading system for events alleging non-combatant or ‘friendly fire’ deaths from Coalition airstrikes. These are:

Confirmed: Where the coalition or an individual ally has accepted responsibility for the killing of non-combatants or allied forces in a particular incident.

Fair: Reasonable level of public reporting of alleged incident from two or more generally credible sources (often with biographical, photographic or video evidence). Crucially, there are also confirmed coalition strikes in the near vicinity for that date. We believe these cases in particular require urgent investigation.

Fair, but with no confirmed strikes: Locations provided by the Coalition in its daily reports can be overly vague, and on occasion it has not reported strikes on particular locales. At other times the Coalition might state categorically that it did not carry out an airstrike at a named location on a particular date – despite fair evidence of an airstrike in the vicinity.

Weak: Single source claims. Even so, these may feature biographical or photographic detail from a reputable source, with coalition strikes also confirmed in the vicinity.

Contested Events: Where there are claims of both coalition and Iraqi or Syrian aircraft having carried out strikes at a location.

Discounted: Those cases where our researchers or others have identified either that those killed were combatants; that no Coalition or Russian strike took place at the location; or where an incident did not appear to result in any civilian casualties.

Additional resources

Airwars monitors media and social media sites in both Iraq and Syria for claims of coalition-inflicted casualties. We also collate reports from regionally-focused groups, and follow up on allegations with the coalition where possible.

Extensive additional civilian casualties are caused by other parties to both the Iraq and Syria conflicts. These include Iraqi and Syrian government forces and allied militias; and militant and terror groups including Islamic State/Daesh, and the al-Nusra Front.

A number of monitoring groups based in the Middle East and elsewhere issue daily reports which cover not just civilians killed by the coalition, but all of those affected by the wars in Iraq and Syria. You can find more information below:
