The UN's secretary general has said the Cold War is "back with a vengeance".

Antonio Guterres also warned about the dangers of escalation over Syria.

The US and its allies are considering launching missile strikes against Syria after a suspected chemical attack, an action which Russia - whose forces are there supporting the government- has said would risk starting a war.

Russia has accused the UK of faking an attack, an allegation Britain dismissed as a "grotesque, blatant lie".

The Cold War, which followed the Allied victory in World War Two, saw the US and its allies facing off for decades with the Soviet Union, of which Russia is the main successor state.

What exactly did Guterres say?

Mr Guterres delivered his warnings at the opening of a bad-tempered UN Security Council meeting.

"The Cold War is back with a vengeance, but with a difference," he said. "The mechanisms and the safeguards to manage the risks of escalation that existed in the past no longer seem to be present."

He urged countries to "act responsibly in these dangerous circumstances".

During the meeting:

The Russian ambassador to the UN, Vassily Nebenzia, accused the US of using the suspected chemical attack as a pretext to overthrow the Assad government and "contain" Russia

The US ambassador accused Syrian President Bashar al-Assad of using chemical weapons at least 50 times in seven years

France's ambassador said Syria had gone "beyond the point of no return" and France would "shoulder its responsibility to end an intolerable threat to our collective security"

What proof is there of a chemical attack?

The US and France have both said they have proof the Syrian government attacked the Eastern Ghouta town of Douma last Saturday, but neither country has officially given further details.

On Friday, US state department spokeswoman Heather Nauert said: "We know for a fact that it was a chemical weapon."

When she was asked whether the US had proof the Syrian government was behind the attack, she said: "Yes."

The suspected attack, in which dozens of people reportedly died, was denied by Syrian President Bashar al-Assad's government.

Rescue workers from the Syria Civil Defence and the Syrian American Medical Society, which supports hospitals in rebel-held areas, said victims were found with foam coming out of their mouths, blue skin and lips, and corneal burns.

On Thursday, unnamed US officials told NBC News they had obtained blood and urine samples from victims which had tested positive for chlorine and a nerve agent.

The US ambassador to the UN, Nikki Haley, told the network: "We definitely have enough proof but now we just have to be thoughtful in our action."

Control over the town has since passed from rebels to the Syrian and Russian military authorities.

A delegation from the Organisation for the Prohibition of Chemical Weapons (OPCW) will arrive in the area of the suspected attack on Saturday.

What are the Russians alleging?

General Igor Konashenkov, a spokesman for Russia's defence ministry, said: "We have... evidence that proves Britain was directly involved in organising this provocation."

In a video produced by the Russian defence ministry two men speaking Arabic say they were working in the casualty ward of Douma's central hospital when they assisted people brought in after the bombing of a multi-storey building.

While they are clearly talking about the suspected chemical attack, both say the bombing occurred on Sunday 8 April when it actually occurred on Saturday 7 April.

The two men say people were suffering from smoke inhalation, not chemical poisoning, but a panic began when one man said they were victims of a chemical attack.

"This is grotesque, it is a blatant lie, it is some of the worst pieces of fake news we've yet seen from the Russia propaganda machine," the UK's UN ambassador, Karen Pierce said.

In a statement, the UK's Foreign and Commonwealth Office said: "This simply shows (Russia's) desperation to pin the blame on anyone but their client: the Assad regime."

What are Western leaders planning?

In the UK, cabinet ministers agreed it was "highly likely" the Syrian government was responsible for the alleged attack and said the use of chemical weapons must not "go unchallenged".

The US president has said Russian President Vladimir Putin bears responsibility for the alleged attack in Douma because of his support for the Syrian government.

On Wednesday he warned Russia that missiles were "coming" but later tweeted that he had "never said when".

What is Russia saying about the risk of war?

Before the Security Council meeting, Mr Nebenzia accused Washington of putting international peace at risk.

"The immediate priority is to avert the danger of war," he said on Thursday.

Senior Russian figures, including the head of the military, have warned that US missiles will be shot down and their launch sites targeted if Russian personnel come under threat.
