A Lebanese politician with close links to the Syrian government confirmed that precautionary measures were being taken throughout Syria.
Trump on Monday promised a decision on Syria within hours, although he did not say when a decision would be implemented.
On Monday, the president said he isn't ruling out military action.
The deal restores President Bashar al-Assad's control over the entire eastern Ghouta - formerly the biggest rebel bastion near Damascus. "We are meeting our military... and we'll be making some major decisions over the next 24 to 48 hours", Trump said.
Initial US assessments have been unable to determine conclusively what materials were used in the attack and could not say with certainty that Assad's forces were behind it.
The Syrian state denied government forces had launched any chemical attack and Russia, President Bashar al-Assad's most powerful ally, called the reports bogus.
She added: "As far as I am concerned, that can be checked over again, but it doesn't help us as we condemn the case".
"I want to get out", Trump said.
Russian Federation and Syria have blamed Israel for an attack on a Syrian military airport on Monday that reportedly killed at least 14 people. Officials said the jamming operation began several weeks ago.
"It is insane to think that Russian Federation is anything but an adversary", Mr. Sasse said.
Assigning responsibility was the domain of investigators from the Joint Investigative Mechanism between the United Nations and the Organization for the Prohibition of Chemical Weapons, which was dissolved after Russian Federation vetoed a renewal of its mandate in November. "Russian Federation wants to undermine our interests at every turn".
The US will respond to the Assad regime's alleged chemical attack against Syrian civilians, US Ambassador Nikki Haley told the United Nations as she excoriated Russian Federation, saying its hands are "covered in the blood of Syrian children".
A USA action similar to last year's would likely not cause a shift in the direction of the war that has gone Assad's way since 2015.
"The downside is the USA president always has clout in media terms, so there may be less attention on the summit".
As a permanent member of the UN Security Council, Russia can veto any substantive resolution.

An American official said the US was discussing with allies whether they would participate in a retaliatory strike.
Washington has threatened to take military action against Syria to punish it for the alleged attack.
Republican Sen. John McCain of Arizona said Assad heard Trump's signal that he wanted to withdraw from Syria and, "emboldened by American inaction", launched the attack.
Away from the UN's deliberations, a prominent Israeli military analyst said on Monday that Israel's reported strike on an Assad regime air base in central Syria early Monday had sent "a moral message that using chemical weapons is not acceptable".
Vice President Pence will make the trip to the Summit of the Americas in Peru instead, Sanders said.
The trip was set to have been Trump's first visit to South America as President.
