Another suspected ISIS chemical weapons attack investigated in Kurdistan Region

Authorities in the Kurdistan said on Friday, according to Reuters, that they are investigating another suspected gas attack by Islamic State (ISIS) against the Kurdish Peshmerga. 

Civilians and Peshmerga alike in the Sinjar area are being treated for nausea and vomiting after ISIS rockets containing a chemical substance were fired at them on Thursday the Kurdistan Region Security Council (KRSC) said on its Twitter page. 

"If confirmed this will be the eight ISIL weaponized chemical attack against Peshmerga. ISIL tactics continue to become more sophisticated," warned the council. 

The KRSC said the American-led anti-ISIS coalition is helping them with the investigation. 

This attack comes the same week that a source within the Organization for the Prohibition of Chemical Weapons (OPCW) said that mustard gas was used against the Peshmerga in August of last year, making 35 of them ill. 

This latest attack however appears to have used chlorine gas, a type of gas that is often used in the Syrian conflict. Chlorine gas is a choking agent and nausea and vomiting are telltale signs one has been exposed to it.
