British Prime Minister Theresa May's decision to expel 23 diplomats and suspend high-level contacts with Russian Federation is a "soft" response unlikely to worry Moscow, but allows for further retaliation, according to analysts. "Nor will we tolerate such a flagrant breach of Russia's worldwide obligations", May told parliament.
The Russian permanent representative to the UN, Vassily Nebenzia, said: "We demand that material proof be provided of the allegedly found Russian trace in this high-resonance event".
"The British government made a choice for confrontation with Russia", the Russian foreign ministry said in a statement.
The UK's deputy United Nations ambassador, Jonathan Allen, told a special meeting of the Security Council that the Organisation for the Prohibition of Chemical Weapons has been called on to go over the British analysis of the attack.
"What happened in Salisbury was the latest in a clear pattern of reckless and unlawful behaviour by the Russian state", Sedwill said in a statement he read to reporters after the meeting, referring to the English city where Skripal was attacked.
Russia's London embassy issued a tweet assessing Russia-UK relations at below zero - Fahrenheit - and said "we're not afraid of cold weather".
Russian media reported Moscow will expel "dozens" of British diplomats. "There is a very clear disconnect between the announcement that Russian Federation is an aggressor state against (Britain). and the level (of) response which is particularly weak", he told AFP.
"They could be used here in NY".
In an emergency session of the Security Council, ambassador Jonathan Allen said the "indiscriminate and reckless" attack was part of a pattern of Russian misbehaviour that threatened global peace and security. Britain's ambassador to North Atlantic Treaty Organisation briefed the envoys on Wednesday.
According to the spokesman, the United Kingdom position is irresponsible, "from the point of view of the violation of worldwide law by the United Kingdom side".
Warren Gatland takes aim as Eddie Jones gets ruthless
England rugby union coach Eddie Jones has apologised for offensive comments he made past year about Wales and Ireland . Best insisted too it would be "madness" to believe England have lost their edge despite those two defeats on the road.
Trudeau said he spoke with Prime Minister Theresa May to offer Canada's support.
"We don't do fantasy politics".
France was waiting for "definitive conclusions", and evidence that the "facts were completely true", before taking a position.
May said the diplomats being expelled were "undeclared intelligence officers" and they had one week to leave the country. German Chancellor Angela Merkel and U.S. President Donald Trump were quick to assure May they took her views seriously.
It is the biggest such action since 1971 when Britain expelled 90 Soviet diplomats who the Foreign Office said had been engaged in active espionage.
The incident has been compared to the 2006 death of former KGB agent Alexander Litvinenko after being poisoned with a radioactive substance in a central London hotel.
British Prime Minister Theresa May visited a policeman in hospital on Thursday after he was poisoned helping a Russian double agent Sergei Skripal and his daughter Yulia, her spokesman said.
"What people want to see is some of the very rich people who are directly associated with Vladimir Putin. whose wealth can be attributed to their relationship with Vladimir Putin, it may be that the law agencies, that the police will be able to put unexplained wealth orders on them, to bring them to justice for their acts of gross corruption", Johnson told BBC.
"To those who seek to do us harm my message is simple: you are not welcome here", May said.
May also said Britain would clamp down on murky Russian money and strengthen its powers to impose sanctions on abusers of human rights, though she gave few details.
