U.S.-led airstrikes targeting the Islamic State group in Iraq and Syria have likely killed at least 459 civilians over the past year, a report by an independent monitoring group said Monday. The coalition had no immediate comment.
The report by Airwars, a project aimed at tracking the international airstrikes targeting the extremists, said it believed 57 specific strikes killed civilians and caused 48 suspected "friendly fire" deaths. It said the strikes have killed more than 15,000 Islamic State militants.
While Airwars noted the difficulty of verifying information in territory held by the IS group, which has kidnapped and killed journalists and activists, other groups have reported similar casualties from the U.S.-led airstrikes.
"Almost all claims of noncombatant deaths from alleged coalition strikes emerge within 24 hours — with graphic images of reported victims often widely disseminated," the report said.
