"The United States needs to develop leverage to get Russian Federation to tell the Iranians to leave Syria, and the best way to achieve that is to make clear to Moscow that we won't leave before the Iranians are out of the picture", he explained.
According to Syrian State TV, the T-4 airbase in Homs in western Syria was battered by "several missiles" in an "attack likely done by the US" early on Monday.
US President Donald Trump earlier blamed the alleged chemical weapons attack in Douma on Russian Federation and Iran, citing their support for Syrian President Bashar al-Assad.
Israel did not acknowledge carrying out the strike.
The Israeli military last February accused Iranian-backed militias of operating at the base, from where it said an Iranian drone that was shot down over northern Israel had been launched.
Russian Federation and Syria deny that chemical weapons were used. The SANA news agency said the people were freed around midnight on Sunday, adding that they had been held by the Army of Islam group since 2013.
The Observatory says it wasn't immediately clear who was behind the attack. At least 100 people were killed, including families found in their homes and shelters, opposition activists and local rescuers said. Iran also could also push back against the United States in places such as Iraq, where USA troops are present.
"When on a given day, the chance for [active military conflict with Iran] are about one percent, now it is about 10%", former prime minister and defense minister Ehud Barak said Tuesday.
"The timing of the strike isn't coincidental", he said.
Israel has repeatedly warned that it will not accept its arch-foe Iran entrenching itself militarily in Syria. "Israel mitigates the risk of an Iranian response", he said.
Russian Federation and Syria have consistently denied all the allegations of chemical attacks during the seven year old Syrian war, and in this instance have accused the rebels of staging a "false flag" incident to trigger United States intervention.
China said that it supports an investigation into a suspected chemical attack on the Syrian rebel-held town of Douma that has provoked global outrage. Area of atrocity is in lockdown and encircled by Syrian Army, making it completely inaccessible to outside world.
