A Russian news site said that "new systems of the type "Tor-M2" reached the airbase of Hameimim, which is a base for the Russian air force, it has a number of Russian jets."

The new Russian air defense weapons were brought to Syria after the Russian Defense Ministry announced that the Western alliance was preparing to launch a new large-scale missile strike against Syria.

According to a news report published earlier that one of the Russian military transport planes made a trip to Syria.
Experts did not rule out that the plane may have carried S-300 systems capable of destroying "hidden" air targets and repulsing massive air strikes on Syria.
