BEIRUT, LEBANON (9:40 A.M.) – A new satellite image revealed a large buildup of Russian warplanes at the Hmeymim Military Airport in western Syria.

Based on the image released by ISI research group, seven Russian IL-76 cargo planes and more than 30 fighter jets were present at the Hmeymim Airport this week.

Furthermore, most of the Russian warplanes in the satellite image above are Su-30 and Su-35 fighter jets.

The recent buildup of Russian warplanes at the Hmeymim Airport comes just days after their Ministry of Defense announced that they would be delivering the S-300 air defense system to Syria.

The Russian Ministry of Defense’s decision to supply Syria with the S-300 system was made after they found Israel responsible for the downing of the IL-20 reconnaissance aircraft on Monday, September 17th.

Israel maintains that they are not to blame for the downing of the IL-20; they hold the Syrian military responsible for the plane’s demise off the coast of Latakia.
