Meanwhile, in a major change to the pre-conflict 2011 status quo, Russian military police began deploying alongside returning United Nations peacekeepers on the Syrian-held Golan and planned to set up eight observation posts in the area, the Defense Ministry in Moscow said.

A week later, Russian Foreign Minister Sergey Lavrov flew to Jerusalem where he met with Israeli Prime Minister Benjamin Netanyahu in talks that focused on the Iranian presence in Syria.
It is therefore no exaggeration to say that Israel is now facing Iranian-trained and financed forces along two fronts in the north of the country: Lebanon and Syria.
Iran has supported Syrian President Bashar al-Assad with weapons, cash and manpower, and Israel has carried out strikes on Iranian military assets in Syria.
Alexander Lavrentyev, Putin's envoy in Syria told state-controlled Sputnik news in Russia the Russian government was taking Israel's security needs in account and claimed the Russians had "managed to attain the pullout of Iranian units 85km from the Israeli border".
