Ali Akbar Velayati, an global adviser to the Leader of the Islamic Revolution who is on an official visit to Moscow, said that Iran's advisory missions in Syria and Iraq will immediately end if the two Arab countries' governments want so. The meeting was focused on regional security and particularly the situation in Syria.
Iran, following the USA withdrawal from the nuclear deal, is facing stiff sanctions and can not afford to lose Russia's support, nor will it be able to provide Assad with the same level of support.
An Israeli official says Prime Minister Netanyahu's latest meeting with Russian President Vladimir Putin ended with Putin expressing understanding for Israel's call for Iranian forces to be ejected from Syria.
In his view, if Russian Federation and Iran withdraw from Syria, "terrorists will come there".
Ayham Kamel, an analyst with Eurasia Group, said Moscow may ask for acceptance of Assad and an eventual withdrawal of US troops from Syria, as Trump has suggested he would like to happen by the end of the year.
Following news reports of the visit, Judge Rodolfo Canicoba Corral requested the arrest of Velayati.
Mr Velayati reaffirmed Iran's firm intention to maintain its presence in Syria, but skirted a question about a possible pullback from the border, saying only that Tehran would not bow to USA and Israeli coercion.
He referred to the US demand for Iran's exit from Syria and Iraq.
Netanyahu, who met with Putin in the Russian capital the previous day, told reporters before departing that he will not tolerate Iranian forces near the Israeli-occupied Golan Heights or anywhere in Syria.
"Putin underlined the importance of political and defense cooperation between Iran and Russian Federation in Syria".
The Israeli army has launched multiple air strikes against Iranian and pro-Iranian targets in Syria, while an American official said that the Israeli army has carried out an attack targeting the site of an Iraqi armed group in eastern Syria on June 17.
"Once Iran's and Russia's support for the Syrian government weakens, terrorists will return there immediately", he stressed. The $750 million deal between Zarubezhneft and Iran's privately owned Dana Energy aims to raise production at the Aban and West Paydar fields, which now produce a combined 36,000 b/d. In exchange, Iran received relief from sanctions.
