Input: (CNN) Nearly 19,000 civilians were killed in Iraq between January 2014 and October 2015 -- a toll the United Nations calls "staggering" in a new report. The report, released Tuesday, outlined the horrific impact that Iraq's ongoing conflict is having on its civilian population. Much of the suffering was attributed to ISIS, the brutal Islamist terror group which has declared an Islamic caliphate across the vast stretches of territory it holds in Iraq and neighboring Syria.
