Unintentionally...

According to amnesty international, the US- led coalition, indiscriminately, killed 1600 civilians in the offensive push against ISIS in Raquaa.
Amnesty produced names of more than 1,000 people reported killed from June to October 2017 in the northern Syrian city.
Amnesty says that its conservative estimate of the number of civilians killed is at least 1,600.

In what it calls the "most comprehensive investigation into civilian deaths in a modern conflict," the rights group accuses the U.S.-led coalition of indiscriminate use of artillery force in densely populated areas.

The U.S. military says its coalition has determined at least 180 civilians were unintentionally killed during that period in Raqqa and that there are still open investigations.
