Since the Syrian civil war broke out in the summer of 2011, more than 500,000 people have been killed. Of that total, some untold number of children and other civilians have been killed by the American-led military coalition, which has fought ISIS in Syria and Iraq since 2014. The Pentagon has only claimed responsibility for 1,302 deaths, while respected nongovernmental organizations like Airwars have used on-the-ground tracking reports to arrive at a figure roughly six times that: 7,263 civilians through the end of 2018.
