Earlier on Wednesday, U.S. President Donald Trump said that American missiles "will be coming" to Syria as Western countries discussed military action over a suspected chemical weapons attack in eastern Ghouta on Sunday.
Last night the United States ambassador to the UN Nikki Haley slammed Russian Federation for blocking a vote calling for a new inquiry into responsibility for use of chemical weapons in Douma after the weekend's apparent attack.
The tweet marks the most detailed indication of what the USA will do in response to an apparent chemical attack in the rebel-held Syrian city of Douma on Saturday.
Over the weekend, Mr. Trump blamed Syrian President Bashar Assad and his global allies, including Russian President Vladmir Putin for the apparent attack that left dozens dead and hundreds injured.
"Our relationship with Russian Federation is worse now than it has ever been, and that includes the Cold War". "We need all nations to work together", President Trump Twitted.
The Pentagon has long criticised Russian Federation for using so-called "dumb bombs", or weapons that lack precision guidance technology, while striking targets in Syria.
The Russian military said on March 13 that it would respond to any USA strike on Syria by targeting any missiles and launchers involved.
"Whatever happens next has to abide by worldwide law", Swedish U.N. Ambassador Olof Skoog told reporters on Wednesday, referring to USA plans for military action.
On Monday, Trump vowed during a Cabinet meeting at the White House that the United States would make "some major decisions over the next 24 to 48 hours" on how to respond to a suspected chemical attack in Syria over the weekend, which he called "atrocious".
The Syrian regime and the Kremlin both deny responsibility of the chemical attack and have questioned whether the attack even happened, despite footage from Douma with strong evidence suggesting a chemical attack. The president urged Moscow to stop the arms race it was conducting, as Russian Federation needed the US' help.
That's likely a reference to U.S. smart bombs that, typically, can evade missile-defense systems and then precisely hit a target.
After Assad's most recent alleged attack, Trump said that "nothing is off the table".
He declared missiles "will be coming" and hit out at Moscow for standing by Syrian President Bashar al-Assad.
The President previously criticised the Obama Administration for telegraphing its military moves in advance.
