Israeli Prime Minister Binyamin Netanyahu warned Syrian President Bashar al-Assad on Tuesday he would be "risking the future" of his regime if he allowed Iran to be entrenched militarily in his
"We will not allow Iran to establish a military presence in Syria," he told reporters alongside visiting US pointman on Iran policy, Brian Hook.
The two men called for an extension of an arms embargo on Iran, archfoe of both their countries, which expires in October.
"I say to the ayatollahs in Tehran: 'Israel will continue to take the actions necessary to prevent you from creating another terror and military front against Israel'" in neighboring Syria, the premier said.
"And I say to Bashar al-Assad: 'You're risking the future of your country and your regime," Netanyahu said.
Israel has launched hundreds of strikes in Syria since the start of its civil war in 2011, targeting government troops, allied Iranian forces and fighters from the Lebanese Shiite militant group Hezbollah.
It rarely confirms details of operations in Syria, but says Iran's presence in support of Assad is a threat to the Jewish state and that it will keep up such attacks.
"We are absolutely resolved to prevent Iran from entrenching itself militarily in our immediate vicinity," said Netanyahu.
Hook focused on the arms embargo, put in place as part of a multilateral nuclear accord signed by Tehran, Washington and other major powers in 2015.
A lifting of that embargo would allow Iran "to freely import fighter jets, attack helicopters, warships, submarines, large-calibre artillery systems and missiles of certain ranges", the US envoy said.
"Iran will then be in a position to export these weapons and their technologies to their proxies such as Hezbollah, (Palestinian groups) Islamic Jihad, Hamas, Shiite militia groups in Iraq and Shiite militant networks in Bahrain and to the Huthis in Yemen," Hook said. "The last thing that this region needs is more Iranian weapons."
The US unilaterally pulled out of the Iran nuclear accord in 2018.
