Medical charity Medecins Sans Frontieres (MSF) said on Tuesday it had treated a Syrian family with symptoms of exposure to chemical agents from an area where ISIS fighters have been battling other rebels. Two adults, a three-year-old girl and a five-day-old baby girl were treated at an MSF-run hospital in Aleppo province, northern Syria, last Friday, the charity said in a statement. They arrived at MSF's hospital an hour after the attack, suffering from breathing difficulties, inflamed skin, red eyes and conjunctivitis. Within three hours they developed blisters and their breathing difficulties worsened, the statement said.
