On August 30, geospatial imaging and intelligence firm ImageSat International released aerial imagery of a suspected Iranian surface-to-surface missile (SSM) facility under construction outside Wadi Jahannam in northwestern Syria. Israeli media reports note that the facility bears resemblance to the Iranian Parchin missile factory which has been associated with Iran’s ballistic missile and nuclear programs. The Wadi Jahannam site lies close to a Russian S-400 antiair missile battery which was deployed in October 2017. A missile research facility nearby at Masyaf was targeted prior to the deployment during a September 2017 Israeli airstrike.
