Investigations conducted during the month of March reveal that US-led coalition airstrikes targeting Islamic State killed 45 civilians, mostly in and around the Iraqi city of Mosul, according to a Pentagon statement released on Sunday.
In each incident, the Pentagon said "all feasible precautions were taken," but the strikes still resulted in "unintentional" loss of civilian life.
The report did not include findings from an ongoing investigation into a March 17 strike targeting Islamic State fighters in Mosul. That strike resulted in more than 100 civilian deaths, according to reports from residents. Last month, the US acknowledged coalition planes conducted a strike "at the location corresponding to allegations of civilian casualties," but did not confirm the reports of high civilian casualties.
