The US has called for a UN Security Council vote on action against chemical attacks in Syria this evening.
The request was made on a proposal for a new inquiry on the use of chemical weapons at 3pm local Washington, DC time (8pm BST)
The US is pushing for a resolution after a Saturday night gas attack on the rebel-held town of Douma, which killed at least 60 people and injured more than a 1,000 others.
President Donald Trump warned on Monday that there would be a ‘big price to pay’ for the suspected attack.
The president has cancelled his first official trip to Latin America to focus on Syria, White House press secretary Sarah Sanders said in a statement on Tuesday.
The announcement read: ‘At the president’s request, the vice president will travel in his stead.
‘The president will remain in the United States to oversee the American response to Syria and to monitor developments around the world.’
Russian foreign minister Sergei Lavrov has also said that Moscow will table a UN resolution calling for an independent inquiry into the attack in Douma.
He announced that Russia would propose a ‘transparent and honest’ investigation at the Security Council.
Moscow has previously insisted there was no evidence for a chemical attack.
A resolution needs nine votes in favour and no vetoes by Russia, China, France, Britain or the US to pass.
