"The neccesary quantity [of air defense systems] can be supplied on a priority basis, it will not require additional burden for the defense insdustry," the chairman of the Russian upper house defense and security committee, Ozerov said.
According to him, "there is nothing special about such deliveries [if the deal is reached] as Syria is at war with terrorists and Russia helps it to fight terror."
The Syrian government forces currently possess Soviet-made S-200 surface-to-air missile systems, also known as SA-5. The Soviet air defense complex is aimed to defend large spaces from potential enemy's bombers and other strategic aircraft.
"It won't violate the norms of the international law or the UN Security Council as air defense systems are defensive weapons, not offensive," the Russian senator said.
Damascus' need in modern air defense systems apparently was driven by the US' launch of 59 Tomahawk cruise missiles at the Syrian military airfield in Ash Sha’irat, located about 40 kilometers (25 miles) from the city of Homs on April 7. US President Donald Trump said the attack was a response to the alleged chemical weapon use in Syria's Idlib, which Washington blames on the Syrian government, a claim Damascus denies pointing out that it has no such weapons since mid-2014. Russia described the attack as an aggression against a sovereign state.
