Fear mounts that ISIS have used chemical weapons against Kurds in Kobani

Doctors who are treating injured people of Kobani have discovered wounds that could have resulted from exposure to chemical weapons and there are fears that the ISIS have laid their hands on such weapons theguardian.com.

Patients who have arrived for treatment have blisters, complain of burning eyes apart from breathing difficulties – such symptoms are usually associated with chemical weapons. Moreover, the patients reported a bad smell which also produced allergic reaction.
It is believed that Islamic State (ISIS) have obtained stocks of ageing but still potent chemical weapons when it seized Iraqi army bases where they were stored. It seems in June, ISIS had taken control of a sprawling complex in the heart of Saddam Hussein’s chemical weapons program.

Moreover, there are doubts that chemical weapons might have been buried or abandoned elsewhere and had escaped the eyes of the watchdogs and were not destroyed by US forces or the Iraqi military.
Incidentally, stocks manufactured prior to 1991 are dirty, corroded and not always easy to identify or use, but are dangerous and can still cause serious injury.
