Trump has slammed Russian Federation for its partnership with "Gas Killing Animal" Assad, spurring concerns that a US strike could lead to a conflict with Russian Federation, which has major military facilities at Tartus and Khmeimim and works cheek-by-jowl with Syria forces that could be targeted.
Antonov released a statement on Twitter saying, "A pre-designed scenario is being implemented".
President Donald Trump and his national security aides on Thursday discussed United States options on Syria, where he has threatened missile strikes in response to a suspected poison gas attack, as a Russian envoy voiced fears of wider conflict between Washington and Moscow.
Russia, which has military forces deployed in Syria in support of the government, warned that U.S. air strikes risked starting a war.
"All responsibility for them rests with Washington, London and Paris".
Antov added that it was not acceptable to insult Russia's president: "Insulting the President of Russian Federation is unacceptable and inadmissible".
Russian Federation says Syria shot down a significant number of the missiles launched in a Western airstrike, using Soviet-designed air-defense systems.
When Syrian President Bashar al-Assad forces launched a chemical weapons attack against civilian targets a year ago, Trump was horrified by the deaths of "beautiful little babies" and quickly ordered a missile strike against a Syrian government airfield, although he listened to top military advisers and made a decision to minimize Russian and other casualties.
On Thursday, British Prime Minister Theresa May won backing from her ministers to take action in Syria and French president Emmanuel Macron said he had proof that the government had carried out the 7 April attacks in Douma.
Two US officials familiar with an investigation of samples from Douma and the symptoms of victims said initial indications that a mix of weaponized chlorine gas and sarin were used in the attack appeared to be correct. "Insulting the President of Russian Federation is unacceptable and inadmissible", the statement continued.
Russian Ambassador to Beirut Alexander Zasypkin cited orders by Putin.
A Syrian military statement says the U.S., Britain and France fired 110 missiles during a joint attack on targets in Damascus and outside.
The minister said "intelligence agencies of a state that is now striving to spearhead a Russo-phobic campaign were involved in that fabrication".
The Saturday attack targeted a hospital in the Duoma region, near the capital of Damascus, which killed 40 people and injured hundreds of others.
The Russian Foreign Ministry also said that following Syrian rebels' withdrawal from the eastern Ghouta suburbs of Damascus, stockpiles of chemical agents were found there. "We have irrefutable data that this was staged", Lavrov said.
Iranian state TV is reporting the country's Foreign Ministry has strongly condemned the USA -led airstrikes on Syria.
Iran is a key ally of Syrian President Bashar Assad and has sent troops to bolster his forces.
USA officials suspect the Russia-backed Assad regime is behind the attack.
The presence of Russian troops and air defenses in Syria were among numerous complications weighing on Trump, who must also consider the dangers to roughly 2,000 American troops in the country if Russia were to retaliate for USA strikes.
