ISIS carrying out chemical experiments on its prisoners as it moves labs into residential neighbourhoods

Islamic State has moved its chemical weapons operation to densely populated residential areas and is testing homemade chlorine and mustard gas on its prisoners, residents of the Iraqi city of Mosul have claimed.

The Islamic State of Iraq and the Levant (Isil) is reported to have set up laboratories in built-up neighbourhoods in the heart of its so-called caliphate to avoid being targeted by coalition air strikes.
