Kurdish officials said Thursday that mortar shells fired last week by Daesh may have been filled with a chemical substance, possibly chlorine, the Associated Press reported.
Nine Kurdish soldiers were admitted to Dohuk hospital with symptoms including vomiting, nausea, shortness of breath, and itching, Dr. Afrasiab Mussa Yones, director of the hospital, told the AP.
Yones says the symptoms suggest a chlorine attack, but that further analysis is necessary.
One of the victims, Col. Lukhman Kulli Ibrahim says that he lost consciousness when the mortar struck, and then struggled to breathe and felt burning sensations in his eyes and chest.
Last year the Organization for the Prohibition of Chemical Weapons confirmed that Daesh had used mustard gas on Kurdish forces in Syria in August.
