Russian Federation recently stated "it would certainly react to any sort of United States missiles shot on Syria by shooting all of them down" and even "targeting their launch locations".
Defence Secretary James Mattis said the United States was still assessing the chemical attack, but added that the military stood ready "to provide military options if they are appropriate as the president determines".
U.N. Secretary-General Antonio Guterres told the Security Council Friday that "there is no military solution to the conflict". "Today, I called the ambassadors of the five permanent members of the Security Council to reiterate my deep concern about the risks of the current impasse and stressed the need to avoid the situation spiraling out of control", he said, referring to the United States, Russia, China, France and Britain.
The Russian Foreign Ministry also said that following Syrian rebels' withdrawal from eastern Ghouta, stockpiles of chemical agents were found there.
The US says "all options are on the table" in response to a suspected chemical weapons attack in Syria, as Western leaders continue to weigh up military action.
"They are the guarantors of law and order in the town", RIA news agency quoted Russia's defence ministry as saying.
At the eye of the storm, Assad said any Western action "will contribute nothing but an increase in instability in the region, threatening worldwide peace and security", Syrian state television reported.
"America does not seek an indefinite presence in Syria under no circumstances", Trump said re-litigating his plan, adding, "As other nations step up their contributions, we look forward to the day when we can bring our warriors home".
"The intelligence provided certainly paints a different picture", Sanders said.
A year ago, Putin was nurturing hopes for better ties with the USA under President Donald Trump.
"We also invited the newly-elected United States president to visit us, because it was presumed that the meeting between Russian and U.S. presidents would be held in Vladimir Putin's native city of St. Petersburg".
The head of the Irbis Society, Andrey Polyakov, told reporters that Donald Trump was awarded the "honorary Cossack" title following the 2016 U.S. presidential election.
Mattis' remarks at a House Armed Services Committee hearing followed a series of Trump tweets this week that initially indicated he was committed to bombing Syria but later suggested he was awaiting further advice and assessment.More news: Volkswagen restructures management and company structure
"Get ready Russian Federation, because they will be coming, nice and new and 'smart!'".
With its increasing tensions with Russian Federation and the prospect of a trade war with China, the United States is at the centre of a lot of global debate and President Trump is at the heart of it. Stop the arms race?
Assad's Damascus regime, which has long accused Washington of supporting its armed opponents in the country's bloody seven-year-old civil war, hit back at Trump's "reckless escalation".
Trump, who has often said a commander in chief should never telegraph his military intentions, apparently did so himself, tweeting that missiles "will be coming" in response to the suspected chemical attack that killed at least 40 people near Damascus.
As it looked to head off the threat of Western strikes, Syria said it had invited the Organisation for the Prohibition of Chemical Weapons, which has blamed the regime for previous attacks, to visit the site. "We are acting together with our American and French allies".
Dunford said the US did not coordinate targets with or notify the Russian government of the strikes, beyond normal airspace "de-confliction" communications.
The U.S. and its allies have threatened to take military action in response to an alleged chemical attack last weekend.
The Security Council met behind closed doors at the request of Bolivia, a supporter of Russian Federation, to discuss the threat of military action against Syria as Trump was huddled with his national security advisors in Washington.
Trump said he was holding meetings on Thursday on Syria, and expected to make decisions "fairly soon".
"Could be very soon or not so soon at all!" The West swiftly pointed the finger at the Syrian government, which has denied the accusations.
Senior US military sources say President Assad's forces have already moved some aircraft in an attempt to protect them from attacks. He said a decision would be made "in due course, when we judge it most useful and effective".
Prime Minister Theresa May recalled the ministers from their Easter holiday for a special cabinet meeting on how to respond to what she has cast as a barbaric poison gas attack by Syrian government forces on civilians in the formerly rebel-held town of Douma, just east of the capital Damascus.
The US gave no details of civilian or military casualties, but its military leaders insisted targets had been chosen carefully to minimise civilian casualties, but maximise the message intended for the Syrian government of President Bashar al-Assad.
