The U.S.-led air war against the Islamic State in Iraq and the Levant has led to hundreds of civilian deaths in Syria and Iraq, according to a report released this week. Next weekend marks the anniversary of the campaign, launched by the Obama administration initially to roll back the jihadists' gains in Iraq. The range of the airstrikes soon expanded to include Syria, as well.

According to Airwars, a London-based group of independent journalists, "there are clear indications" that at least 459 civilians have been killed as a result of the strikes. It pointed to 57 incidents where noncombatants were likely killed by coalition airstrikes.
