Iraq says ISIS hit troops with chemical gas

Anxiety grows as ISIS nears Iraqi capital

A senior security official, a local official from the town of Duluiya and an official from the town of Balad say ISIS used bombs with chlorine-filled cylinders during September clashes.

They told The Associated Press on Friday that about 40 troops and militiamen were slightly affected by the chlorine and showed symptoms consistent with chlorine poisoning, such as difficulty in breathing and coughing. They were treated in hospital and quickly recovered.

The three spoke on condition of anonymity because they are not authorized to speak to media.
