Chemical weapons experts are due to arrive in Douma on Wednesday to probe an alleged poison gas attack, Russian officials said, as the USA voiced fears Moscow may already have "tampered with" evidence at the site.
The President is said to be distressed that the U.S. ended up expelling far more Russian diplomats than any other country, when he simply wanted to do the equivalent.
The Kremlin dismissed claims that Russian Federation was impeding access.
A senior Russian diplomat said on Monday that the mission from the global chemical weapons watchdog can not access the site of an alleged chemical attack near the Syrian capital without an appropriate United Nations permit. Russia's inability to prevent the airstrikes from succeeding, along with the failure of Russian mercenaries to overwhelm USA forces in February, have left the Kremlin stewing while continuing to color the U.S.as a pushover.
"Chemical weapons were used on Syrian men, women, and children in Douma". The supporting actors understood they had no choice but to watch the USA finesse its way out of a sticky situation. More than 6.1 million people have been displaced but remain in Syria.
"When you look at what Russia has done, not just in this country, in Salisbury, attacks on TV stations, on the democratic processes, on critical national infrastructure - of course we have to be very, very cautious indeed", Johnson said on the BBC's Andrew Marr Show on Sunday, when asked about the possibility that Russian could launch cyber-attacks on the National Health Service or electricity grid.
Deputy Russian Foreign Minister Sergei Ryabkov blamed the Western air strikes carried out early on Saturday for holding up a mission by the OPCW team to Douma.
"I can guarantee that Russian Federation has not tempered with the site", Lavrov told BBC in an interview.
Syrian President Bashar Assad praised the quality of Soviet-made air defense systems that he argues resulted in the failiure of the U.S., U.K., and French bombing attack inSyria Saturday, Russian lawmakers said after a meeting with the Syrian president in Damascus Sunday.
Many in Washington have expressed doubt that the goals of deterring chemical weapons attacks in Syria, while also taking control of the final pockets of territory controlled by the Islamic State along the Syrian-Iraqi border, can possibly be reconciled with President Donald Trump's insistence on immediately withdrawing the some 2,000 US troops deployed at a series of small bases in northeastern Syria.
If anything, the US-led strike become a major blow to the Chemical Weapons Convention - a 1997 agreement to which the USA is a party - the expert argued. Failure to act to hold perpetrators to account will only risk further barbaric use of chemical weapons, in Syria and beyond. Footage of young victims foaming at the mouth and weeping in agony helped to thrust Syria's civil war - in which half a million people have been killed in the past seven years - to the forefront of world concern again.

"Nobody can imagine someone who uses chemical weapons against his own people to be part of this solution", he added.
Russia - Syria's ally - has said worldwide chemical weapons experts are due to arrive in the area on Wednesday to check the claims.
Russian Federation told the United Nations last Friday that its experts found no trace of "toxic substance use" during their investigation in Douma. Of course. But there are several things to bear in mind, beginning with the fact that, as recently as February, Secretary Mattis admitted that the United States had "no evidence" that Assad was behind the alleged chemical attack in April of a year ago.
Russia's response thus far has been a mixture of indignation and threatening posturings.
The G-7 say they "fully support all efforts made by the United States, the United Kingdom and France to degrade the (Bashar) Assad regime's ability to use chemical weapons and to deter any future use" with the strikes.
