Mr Trump did not give a time-frame for any retaliatory action, but said the U.S. could not stand by as such atrocities take place because "we are able to stop it". The ship is armed with Tomahawk cruise missiles, the weapon of choice in a US attack one year ago on an airfield in Syria after an alleged sarin gas attack on civilians at Khan Sheikhoun.

"This is about humanity - it can't be allowed to happen", he said. "And we'll be letting you know pretty soon - probably after the fact".

In the course of the liberation operation in Eastern Ghouta, which began in February, Moscow has repeatedly warned that the militants in the region could stage gas attacks in a bid to frame the Syrian government.

Diplomats said that the resolution would likely be vetoed by Syrian ally Russian Federation. "Everybody's going to pay a price".

US President Donald Trump has cancelled his first official trip to Latin America to focus on the issue of a suspected chemical attack in Syria.

Following a chemical attack in northern Syria previous year, Trump launched airstrikes against Syria.

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.

Earlier, the Russian Foreign Minister Sergei Lavrov said specialists had visited the area of the alleged attack and did not find any trace of chlorine or any other chemical substance used against civilians.

The line-up among the global parties involved in the Syrian conflict - France, Iraq, Lebanon, Russia, Saudi Arabia, Turkey, and the United States, as well as the Kurds - also bears on what happens next in Syria.

The Security Council held an emergency meeting to discuss the chemical attack and the council president said experts were working on a resolution on the continuing use of chemical weapons in Syria, but sharp differences remain between Russian Federation and the United States and its allies.

Sanders said Trump has made a decision to stay in the United States to "oversee the American response to Syria and to monitor developments around the world".

The United States and its allies have cited circumstantial evidence to blame the Syrian military for the attack.

Vladimir Shamanov, a retired general who heads the defense affairs committee in the lower house of parliament, said in televised remarks Tuesday that a USA strike in Syria could hurt Russian servicemen and trigger Russian retaliation.

The Organisation for the Prohibition of Chemical Weapons said Syria has been asked to "make the necessary arrangements for such a deployment". Syria denies being behind any chemical attack. "It was filmed on the H shaped building at [geographic coordinates] 33.573900, 36.404831, which we've confirmed by geolocation", said Bellingcat founder Eliott Higgins.

The United States is looking to the UK and France for support as it finalises its response to the assault on the rebel-held town of Douma.

Trump - who past year launched a missile strike on a regime base after another alleged chemical attack - warned Sunday that there would be a "big price to pay".
