The ISIS terrorist group may have used chemical weapons against U.S. and Iraqi troops in northern Iraq, according to a report from CNN, citing unnamed U.S. officials.
ISIS forces reportedly fired an artillery shell or a rocket that might have contained a mustard agent onto an Iraq military base. No American soldiers were injured or have showed symptoms of exposure to mustard, CNN reported.
U.S. troops tested it, showing an initial reading of the mustard chemical agent.
