Foreign Minister Sergei Lavrov said in a meeting with his counterparts from Poland and Germany in Warsaw that the missile package was already sold to Syria and the delivery process was underway now.

Tensions run high in the region after Israeli regime carried out an aggressive attack on a research center near capital, Damascus, in May 5th which drew international condemnation.

Russian President Vladimir Putin, whose country remains a main supporter of the Syrian government against the more than two-year deadly insurgency, warned Israel against any further aggression on Syria.

During a phone conversation with Israeli Prime Minister Benjamin Netanyahu, Putin said that “Russia would not tolerate further Israeli attacks on Damascus and would respond.”

Syrian government described Israel’s assault as a declaration of war which opened the door "to all possibilities", making the situation in the region more dangerous.
