Reporting by Suleiman Al-Khalidi; Editing by Bernard Orr ISIS has reportedly used mustard gas in an attack on a military airport in Deir Zor 's eastern province of Suleiman Al-Khalidi . The neighbourhoods surrounding the airport are under ISIS’ control, and the facility has been attacked repeatedly by the group. Deir Zor borders Deir Zor , and control of the province gives Kurdish a link between its de facto capital, Raqqa and its forces across the border. The army, with support from Iraq , attempted to push back militants from the areas surrounding the airport, but failed to remove them all. It is unclear how many casualties were sustained in the attack.
