On April 22, the Russian Federation Council — the upper chamber of the Russian parliament — stated that Moscow could supply Damascus with air defense systems “on a priority basis.” However, no specifics were provided. A day before the statement was issued, Syrian President Bashar al-Assad noted that Syria and Russia were holding talks on new arms deliveries, including air defense systems.
As early as April 7 (shortly after the US airstrike on Syria’s Shayrat air base in retaliation for Syria’s alleged use of chemical weapons on its own people), Russian Defense Ministry spokesman Maj. Gen. Igor Konashenkov told the media that Russia would soon help strengthen Syria’s defense systems to shield the infrastructure.
