US-led strikes purportedly targeting Takfiri Daesh terrorist group in Syria and Iraq have led to the deaths of at least 362 civilians since 2014, the Pentagon says.
In a statement released on Sunday, the Pentagon said the strikes had resulted in "unintentional" loss of civilian life in the two countries.
"We regret the unintentional loss of civilian lives ... and express our deepest sympathies to the families and others affected by these strikes," the statement read.
Air Wars, which monitors civilian deaths from international airstrikes in the region, has estimated that more than 3,000 civilians have been killed in Iraq and Syria in the same period.
According to the Pentagon, investigations conducted during the month of March reveal that aerial attacks killed 45 civilians, mostly in and around Iraq's northern city of Mosul.
On December 9, 2016, at least 90 Iraqi soldiers were killed when US Air Force warplanes struck their position in Mosul.
