Britain's U.N. ambassador is vehemently denying a Russian military claim that the United Kingdom staged an alleged chemical attack in Syria last weekend, calling it "bizarre" and "a blatant lie".
On Wednesday, Trump warned Russian Federation to brace for US engagement in Syria, after a suspected chemical attack in Eastern Ghouta's Douma killed dozens. "It's some of the worst piece of fake news we've yet seen from the Russian Federation propaganda machine".
Asked if he had seen enough evidence to blame Assad, Mattis said: "We're still working on this". #The United States - along with the UK and France - have already formed an alliance and are considering military action in Syria. Again, we are being threatened.
Iran's Fars News Agency reported Friday that Russian fighter jets were patrolling Syrian air space to defend against any attackers.
As ministers discussed the crisis yesterday, USA officials claimed to have evidence that chlorine gas and a nerve agent were used in a Syrian government attack on the town of Douma in Eastern Ghouta at the weekend that left around 70 dead.
"The situation in the world is becoming more chaotic", he continued, "nevertheless we still hope that common sense will eventually prevail"- seemingly alluding to Trump's dramatic tweet.
Foreign ministry spokeswoman Maria Adebahr said Germany agreed with its allies that the use of chemical weapons must not go unpunished.
The chairman of the worldwide affairs committee of Russia's upper house of parliament, Konstantin Kosachev, said the strikes were a violation of worldwide law and probably created to prevent investigators from the global chemical weapons watchdog from doing their work.
The OPCW said it would "shortly" deploy a fact-finding team to Douma for an investigation, but USA officials said they were working from their own information and would not necessarily hold back.
"God forbid anything adventurous will be done in Syria following the Libyan and Iraqi experience", he stressed.
"The immediate priority is to avert the danger of war", Russian's ambassador to the UN, Vassily Nebenzia, told reporters following a closed-door meeting of the Security Council. Mr. Trump called out Putin along with the leadership in Iran for backing Assad, who he referred to as "Animal Assad".
The capture of Douma from rebels who evacuated this week has clinched a major victory for Assad, crushing what was once a centre of the insurgency near Damascus, and underlines his seemingly unassailable position in the war.
Trump held meetings with his national security advisers and conferred with France and Britain on the Syrian situation throughout the day on April 12.
Moscow and Washington blocked attempts by each other at the United Nations Security Council on Tuesday to set up worldwide investigations into chemical weapons attacks in Syria.
"Our president has not yet made a decision about possible action in Syria".
The Security Council is scheduled to meet on Thursday at the request of Bolivia, which wants to discuss the escalation of rhetoric over Syria and threats of unilateral military action. After alleging the strike was associated with chemical facilities and storage sites, US Chairman of the Joint Chiefs of Staff Joe Dunford said it was a one-time strike, and it was completed in less than 60 minutes.
