Adding to the tensions, Iran, a strong ally of Syrian President Bashar Assad, threatened to respond to an airstrike on a Syrian military base on Monday that the Syrian government, Russian Federation and Iran blamed on Israel.
In response, Russia's Foreign Ministry said in a Facebook post that "smart missiles should fly towards terrorists, not towards the lawful government".
The Syrian government strongly denied involvement, and Russian Federation issued a stark warning in an attempt to halt retaliation.
The president discussed possible military action that could be taken during a meeting with military leaders on Monday.
"You do not want to hear the fact that no traces of a chemical attack were found in Douma, " Nebenzia said.
"So he's doing the exact same thing that he criticized his predecessors for doing".
A spokesman for President Vladimir Putin said the strike dealt a "significant blow to relations between Russian Federation and America, which are already in a poor state". "There is no reason for this". Russian Federation needs us to help with their economy, something that would be very easy to do, and we need all nations to work together. "Stop the arms race?"
Options include limited military strikes, such as the Tomahawk missiles launched from a U.S. Navy destroyer in the Mediterranean targeting a Syrian airstrip nearly exactly a year ago after an alleged chemical attack on Khan Sheikhoun in Idlib that killed more than 100 people.
The Russian military said on March 13 it would respond to any United States strike on Syria, targeting any missiles and launchers involved in such an attack.
Options for USA retaliation against the Syrian government over an alleged chemical attack on a rebel-held neighborhood near Damascus on Saturday run the gamut from light to heavy impact, according to a US official.
That incident, which killed hundreds in the deadliest use of toxic gas, also took place in Eastern Ghouta, where Douma is located. The tweet came as Trump administration officials have consulted with global allies on a possible joint military response to Syria's alleged poison gas attack. "We have a lot of options, militarily", he said.
Syria became a member in 2013 as part of a deal brokered by the US and Russian Federation after a chemical attack in eastern Ghouta killed hundreds of people. That's where the US said planes had taken off before carrying out a chemical weapons attack on civilians in a nearby town, Khan Shaykhun.
That decision suggests the USA response may involve a larger military operation than a limited strike, says the BBC's Barbara Plett Usher in Washington. Mr Trump entertained a question about firing Mr Mueller while speaking with reporters, but did not say whether he was considering the move.
Last year's strike targeted aircraft and aircraft shelters, ammunition, air defense systems and radar gear.
"This time around, I do think it has to be different".
"They have threatened us a thousand times".
Israel's Haaretz newspaper speculated that the claim was an indication that Syria's ruling Assad regime was revealing new capabilities.
The UN Security Council held emergency meetings Monday on Syria, which sees tensions between the representatives of the United States and Russian Federation.
Russian Ambassador to the United Nations Vassily Nebenzia, who spoke after Haley, argued that the US draft prejudges the outcome of an investigation.
The Eurocontrol airspace organisation said the European Aviation Safety Agency had sent a "rapid alert notification" that flight operations needed to consider the possibility of air or missile strikes into Syria.
Last year, the United States launched missile strikes from two Navy destroyers against a Syrian airbase after the Syrian government was said to be responsible for chemical weapons use.
In its statement, the Foreign Ministry, repeated its line that Washington's allegations were "unsubstantiated" and that the alleged chemical attack is being used as a pretext to target Syria. The Syrian Observatory for Human Rights, a war monitoring group, said 14 people were killed in that attack.
Doctors have said that the symptoms presented by suspected victims of the attack are consistent with chlorine gas.
The request from the OPCW Technical Secretariat to the Syrian government was announced just as Russian Federation was telling the U.N. Security Council it would put two draft resolutions on Syria to a vote on Tuesday, after rejecting a similar proposal from the US following an angry debate at the council Monday.
"I am not like other administrations, where they say, 'We are going to do this in four weeks.' It doesn't work that way".
