Iranian forces have withdrawn their heavy weapons in Syria to a distance of 85 kilometers (53 miles) from the border with Israel on the Golan Heights, TASS quoted a Russian envoy as saying on Wednesday, but Israel deemed the pullback inadequate.

Backed by Russia, Iran, and Lebanon’s Hezbollah Shi’ite militia, Syrian President Bashar al-Assad has retaken territory in southwestern Syria from rebels, closing in on the Golan.

Moscow has sought to reassure Israel by saying it wants only Syrian forces to deploy on or near the Syrian side of the Golan. Israel, however, insists that forces controlled by Iran, its arch-foe, exit Syria entirely now the civil war there is ending.

“The Iranians withdrew and the Shi’ite formations are not there,” TASS news agency quoted Alexander Lavrentiev, President Vladimir Putin’s special envoy to Syria, as saying.

Lavrentiev said Iranian service personnel whom he described as advisers could be among Syrian army forces who remain closer to the Israeli border.

“But there are no units of heavy equipment and weapons that could pose a threat to Israel at a distance of 85 kilometers from the line of demarcation,” Lavrentiev said.

An Israeli official deemed such a pullback insufficient.

“What we have laid down as a red line is military intervention and entrenchment by Iran in Syria, and not necessarily on our border,” Regional Cooperation Minister Tzachi Hanegbi told Israel Radio, citing the longer-range threat posed by Iranian missiles or drones positioned in Syria.

“There’ll be no compromises nor concessions on this matter.”

Last week an Israeli official, who spoke on condition of anonymity, said Russia had offered to keep Iranian forces at least 100 kilometers from the border.

Israel rejected the offer, which was made during a meeting between Prime Minister Benjamin Netanyahu and visiting Russian Foreign Minister Sergei Lavrov. In an apparent riposte, Russia’s ambassador to Israel, Anatoly Viktorov, said on Monday that Moscow could not compel Iran to leave Syria.

But Viktorov also signaled that Russia would continue to turn a blind eye to Israeli air strikes against suspected Iranian and Hezbollah arms transfers or emplacements in Syria.

Hanegbi said Israel wanted to prevent Iran and Hezbollah from effectively extending their Lebanese front against it.

“We are not ready to see a new Hezbollah front on our northern border between Israel and Syria. This is something that is dangerous. This is something that, if we don’t prevent it today, when still at its outset, will a exact a heavy price of us down the line,” he said.
