Syria chemical weapons: finger pointed at jihadists

"However a senior source close to the Syrian Army has given Channel 4 News the first clear account of what he claims is believed to have occurred on Tuesday. He is a trusted and hitherto reliable source who does not wish to be identified. The Syrian military is said to believe that a home-made locally-manufactured rocket was fired, containing a form of chlorine known as CL17, easily available as a swimming pool cleaner. They claim that the warhead contained a quantity of the gas, dissolved in saline solution. The source said that the town of Khan al-Assal has been in government control since March 13 but - like so much of the area - has been much fought over and parts of the area change hands with relative frequency. Rebel Sunni groups with al-Qaeda sympathies have been attacking the town, where the population is predominantly Shia. The military's version of events is that the home-made rocket was fired at a military checkpoint situated at the entrance to the town. The immediate effects were to induce vomiting, fainting, suffocation and seizures among those in the immediate area. A second source - a medic at the local civilian hospital - said that he personally witnessed Syrian army helping those wounded and dealing with fatalities at the scene. That Syrian soldiers were among the reported 26 deaths has not been disputed by either side."
