The allies reportedly had conclusive evidence that Syria used chemical weapons on its own people.
Videos broadcast by Russian and Syrian media last week showed Russian troops visiting the building where the footage was filmed, and Russian Foreign Minister Sergei Lavrov told reporters that they had found no evidence of a chemical attack there. And it would establish a new body to determine responsibility for chemical attacks, call for a cease-fire in Syria, unimpeded access for all humanitarian aid, and an urgent resumption of negotiations on a political settlement. Syria's civil war, which began as a popular uprising against Assad, is now in its eighth year.
Vassily Nebenzia, Moscow's U.N. ambassador said he "cannot exclude" war between the United States and Russian Federation.
The Syrian government now has control of eastern Ghouta and the town of Douma where they are flying the Russian flag next to Syria.
He said Moscow has "irrefutable information that it was another fabrication" and that "intelligence agencies of a state that is now striving to spearhead a Russo-phobic campaign were involved in that fabrication".
The U.S. ambassador to the United Nations, Nikki Haley, said President Donald Trump "has not yet made a decision about possible actions in Syria".
A Russian defense ministry official said later the OPCW experts would travel to Douma on Wednesday.

Sheikh Naim Qassem, deputy leader of the Iranian-backed Hezbollah movement, told Lebanese daily al-Joumhouria: "The conditions do not point to a total war happening. unless Trump and (Israeli leader Benjamin) Netanyahu completely lose their minds".
"We have not done this because President Trump asked us to, we have done it because we believed it was the right thing to do, and we are not alone".
Later, speaking at the meeting, called by Russian Federation to discuss the prospect of an American strike on Syria, Haley said, "This meeting should not be about so-called 'unilateral threats, ' it should be about the multiple actions Russian Federation has taken to bring us to this point".
May has said she did not seek a green light from parliament for the attacks, citing the need to act quickly.
