Xendan, a news agency in South Kurdistan, says that the ISIS (Islamic State of Iraq and al Sham) gangs used chlorine gas against the Iraqi army units to the north of Baghdad.

A video broadcast by Xendan shows a group of Iraqi soldiers who were found unconscious on a river bank. The soldiers said they were overcome by thick yellow smoke after an explosion. An eyewitness confirmed what had happened to the CNN Arabic channel.

The chemical attacks by the ISIS gangs came onto the agenda after the gangs  launched an attack on Kobanê. Now the Iraqi army has also became the victim of a chemical attack by the ISIS gangs. It is accepted that chlorine gas is a chemical weapon with lethal effects. It can also be used in shells.

This incident which was also experienced in Kobanê occurred in Iraq last month. The US Secretary of State John Kerry said that they are taking seriously the claims that the ISIS gangs used chlorine gas against the Iraqi security forces and they are investigating the claims.

The Washington Post newspaper wrote Friday that 11 Iraqi police officers were taken to a hospital in Bagdad with nausea, vomiting and difficulty in breathing. The Iraqi police officers were diagnosed with poisoning by chlorine gas.
