Russia's ambassador to the USA warned that there would be consequences for the attacks early on Saturday, which came in response to a suspected chemical weapons attack in the former rebel stronghold of Douma last weekend.
In response to the US military action, Russia's ambassador to the US Anatoly Antonov said in a statement that Russian Federation had warned that "such actions will not be left without consequences". Both Syria and Russian Federation have denied involvement in the attack, and Russian Federation claimed on Friday that the event was "staged" by the United Kingdom.
Russia's Foreign Ministry claims that no evidence of chemicals or deaths in the bombing area were found in its inspection. They are expected to arrive on Saturday.
"We have irrefutable evidence that this was another staged event, and that the secret services of a certain state that is now at the forefront of a Russophobic campaign was involved in this staged event", he said during a press conference.
The White House says it is continuing to assess intelligence and talk to its allies on how to respond.
Why is the West considering military action?
White Helmets first-responders and Syrian activists have claimed the suspected chemical attack was carried out by the Syrian government on April 7 and killed more than 40 people in Douma, allegations that drew global outrage and prompted the United States and its allies to consider a military response.
It comes after UK Prime Minister Theresa May spoke with President Trump and the pair agreed "the Assad regime had established a pattern of unsafe behaviour in relation to the use of chemical weapons". "The nations of the world can be judged by the friends they keep", he said.
The Kremlin on Saturday condemned Western air strikes on Syria where its armed forces are backing President Bashar al-Assad.
The final evacuations of about 4000 remaining Islamist fighters and civilians were taking place on Friday, according to the UK-based Syrian Observatory for Human Rights monitoring organisation.
The council failed on Tuesday to approve three draft resolutions on chemical weapons attacks in Syria.
The Violations Documentation Center (VDC), which records alleged violations of worldwide law in Syria, said bodies were found foaming at the mouth, and with discoloured skin and burns to the eyes.
US Ambassador Nikki Haley said no decision had been taken on military action and stressed the importance of carefully assessing all the implications.
The call for action came after a suspected chemical attack on the rebel-held town of Douma in the Eastern Ghouta last week killed over 70 people.
Later, a White House briefing on a call between Trump and May said that they "continued their discussion of the need for a joint response to Syria's use of chemical weapons".
Mr Jaffer, a former advisor to US President George W. Bush, argued the Assad regime in Syria would not exist if it was not for the support of Vladimir Putin, claiming the Russian President was also to blame for the deadly civil conflict.
