Islamic State Use Mustard Gas Against Iraqi Kurds
Sources from the global chemical watchdog say Islamic State (IS) militants used sulphur mustard (mustard gas) in an attack on Iraqi Kurdish forces last year. Lab tests came back positive for the substance after Kurdish soldiers fell ill on the battlefield. The BBC reports: The Organisation for the Prohibition of Chemical Weapons (OPCW) was sent samples after 35 Peshmerga fighters became ill near Irbil in August. On Monday, the sources said the samples tested positive for sulphur mustard.
