ISIS may have used chemical weapon on US, Iraqi troops
WASHINGTON - ISIS forces fired a shell that may have contained a chemical agent onto a military base in northern Iraq on Tuesday while US and Iraqi troops were present, CNN reported on Wednesday, citing several US officials.
No US troops were hurt in shelling at the base, which is being used to prepare an attack to retake Mosul from ISIS, CNN said. The first test came back positive for a mustard agent but the second test was negative, it said.
