It comes after the French foreign minister said France wants to start working "right now" on resuming the political process aimed at ending the conflict in Syria. He urged Moscow to call on Damascus to put an end to the suffering of Syrians.
Damascus, with key allies Russian Federation and Iran, have lambasted reports of the suspected gas attack as bogus.
In a statement, OPCW, the chemical weapons watchdog of the United Nations, has said its fact-finding team will continue to investigate allegations of the use of chemical weapons in Douma where 70 people reportedly died due to an exposure to chemical attack. "They are crimes of a monster instead". The Pentagon clarified on Saturday that this year's strikes involved 105 missiles, compared to 59 last year. A Security Council diplomat said the body would meet later Saturday.
There are no reported civilian casualties and authorities in Damascus have said the buildings were evacuated before they were hit.
"We assess that this was the primary location of Syrian sarin and precursor production equipment", Dunford said.
"We are confident that all of our missiles reached their targets", said Lt. Gen. Kenneth McKenzie, the director of the Joint Staff at the Pentagon.
'Large part' of Syria's chemical arsenal destroyed in air strikes: France: The French foreign minister Jean-Yves Le Drian told on the last Saturday that missile strikes can be carried out overnight in the nation Syria by Britain, France, and the U.S. had destroyed a "large part" of the Damascus government's stocks which are of the chemical weapons.
"But we will not stand passively by while Assad, backed by Russian Federation and Iran, ignores global law". "We invite Russian Federation to start supporting the innocent men, women and children of Syria who are being killed with chemical weapons", the U.S. ambassador said.
"I spoke to President Trump this morning and he said if the Syrian regime uses this poisonous gas again, the United States is locked and loaded", Haley said at an emergency U.N. Security Council meeting called by Russian Federation.
She added that the strikes were not about "regime change".
While Germany did not take part in the action against Syria, Chancellor Angela Merkel said on Saturday she supported steps taken by the allies.
It was not immediately clear how extensive the strikes were.
Russian president Vladimir Putin has denounced the missile strikes by the US, France and the United Kingdom as an "act of aggression" that would exacerbate the humanitarian catastrophe in Syria.
U.S. officials said that ship-launched missiles and planes were involved in the attacks, and British officials said that missiles launched from GR4 Tornados warplanes had hit a plant near Homs believed to be used for precursors for making chemical weapons.
Russian President Vladimir Putin called strike an "act of aggression against a sovereign state" and claimed they went against the United Nations charter.
