The US-led coalition fighting the IS group in Syria and Iraq acknowledged Thursday the deaths of another 10 civilians, increasing the overall toll of non-fighters killed to at least 841.
The coalition said in a statement that it had completed a review in January of 116 reports of potential civilian casualties from air and artillery strikes, of which all but four were deemed to be duplicates or not credible.
These four incidents occurred in Syria between October 2016 and November 2017.
In one instance, five civilians were killed during a coalition attack on IS trucks and fuel tankers.
“The investigation assessed that although all feasible precautions were taken and the decision to strike complied with the law of armed conflict, unintended civilian casualties unfortunately occurred,” officials said in a statement.
Investigators were still looking at another 485 reports from the campaign.
The coalition conducted a total of 29,070 strikes between August 2014 and January 2018 in Iraq and Syria.
Monitoring group Airwars says the number of civilian deaths acknowledged by the US-led coalition is well below the true toll of the bombing campaign, estimating that at least 6,136 civilians have been killed.
The US-led operations to fight IS in Iraq and Syria have largely wound down, with the jihadists ousted from more than 98 percent of the territory they once held.
