ISIS Used Chlorine Against Iraqi Cops: Report Patients in Syria suffer after possible chemical weapon attack By Matt Cantor, Newser User Posted Oct 24, 2014 3:27 PM CDT 22 comments Comments Iraqi federal policemen search a car at a checkpoint in Baghdad, Iraq, Saturday, Oct. 11, 2014. (AP Photo/Karim Kadim) (Newser) – On the heels of reports that ISIS militants are learning to fly fighter jets, Iraqi officials say the group has also used chemical weapons—specifically, chlorine gas. Eleven Iraqi police officers were hospitalized on Sept. 15 after being poisoned by the stuff, according to doctors, and the officers say ISIS was to blame. An Iraqi defense official has confirmed the case, the Washington Post reports. Iraqi security forces have reported two other such attacks, though the details are hazy, the Post notes. Meanwhile, a clinic in Kobani, Syria, received patients suffering from breathing trouble and blisters following the sound of an explosion Tuesday night, the Guardian reports. "Some had red patches and blisters on their skins, others had difficulties breathing and others were vomiting, with painful throats, and others with burning eyes and noses. There was one patient ... all his body was covered in red patches and blisters," says a doctor, who believes a chemical other than chlorine was used in this case. Though chemical weapons have recently been used in Syria, these instances appear to be the first confirmed use of chlorine gas in Iraq in years, the Post reports. The US is investigating the case in Iraq, the BBC reports. All eleven of the officers were discharged from the hospital the next morning.
