Russian Federation has been criticised for vetoing an inquiry into alleged chemical weapons attacks in Douma and obstructing the work of the Hague-based Organisation for the Prevention of Chemical Weapons (OPCW), but Blok said sanctioning Moscow would be counterproductive.
Russian Federation suggested the missile strikes launched by the UK, US and France were part of the reason why the chemical weapons watchdog could not travel to the scene of the attack. "It is our concern that they may have tampered with it with the intent of thwarting the efforts of the OPCW fact-finding mission to conduct an effective investigation".
The prime minister will say the UK joined the United States and France in co-ordinated strikes following the chemical weapons attack in Douma to "alleviate further humanitarian suffering".
He also urged Syria to "end this charade", "immediately cease all" such attacks and "immediately declare and dismantle all aspects of its chemical weapons program". She also said the US would "never" agree to direct talks with the Syrian regime, saying the government of President Bashar Assad is "not worthy" of one-on-one engagement.
"I can not be impolite to the heads of other states ... but frankly speaking, all the evidence they quoted was based on media reports and social networks".
Inspectors have not yet been granted access to sites in Douma, the British delegation to the OPCW said Monday, citing the agency's director general.
Britain has said there are no plans for future strikes against Syria, but Johnson warned Assad that all options would be considered if chemical weapons were used against Syrians again.
Mr Lavrov also questioned why the US, UK and France had carried out their retaliatory air strikes before OPCW inspectors were able to visit the site.
The team was still not been granted safe passage on Monday, CNN quoted British envoy to the OPCW, Peter Wilson, as saying.
Syria and Russian Federation deny chemical weapons were used in the final offensive that captured Douma, a rebel-held territory east of Damascus.
Haley made clear the United States won't be pulling troops out of Syria right away, saying U.S. involvement there 'is not done'.
What was targeted on Saturday? "But it was the world saying that we've had enough of the use of chemical weapons".
Trump tweeted "Mission Accomplished" on Saturday after U.S., French and British warplanes and ships launched more than 100 missiles almost unopposed by Syrian air defenses.
However, Mr Macron said that by joining forces with France and the United Kingdom for last Saturday's air strikes, the U.S. "fully realised that our responsibility went above and beyond the war against IS, and that it was a humanitarian responsibility as well on the ground".
In his televised address from the White House on Friday, Trump said the United States was prepared to keep up the economic, diplomatic and military pressure on Assad until he ends a pattern of killing his own people with internationally banned chemical weapons.
"The US mission has not changed - the president has been clear that he wants US forces to come home as quickly as possible".
A visit by chemical weapons inspectors to the site of a suspected gas attack in Syria was delayed on Monday, British and Russian officials said, as Western powers and Russia traded accusations in the aftermath of retaliatory US -led missile strikes.
"The European Union will continue to consider further restrictive measures against Syria as long as the repression continues", they said in a statement after their talks.
"It was retaliation, not an act of war", Macron said in justifying the operation a day before the French parliament was set to debate it.
