>> Russia's now set to deport some British diplomats by Tuesday as the crisis over the Sergei Skripal nerve agent incident continues to spiral. Its retaliation for the UK's decision to kick out 23 Russian officials on their own soil who Prime Minister Theresa May contends were spies working under diplomatic cover.
>> Our quarrel is with Putin's Kremlin and with his decision. And we think it overwhelmingly likely that it was his decision to direct the use of a nerve agent on the streets of the UK, on the streets of Europe, for the first time since the Second World War.
>> Russia has refused to explain how former spy Skripal and his daughter Yulia could have been exposed to a chemical weapon in the UK that British authorities say was developed in the former Soviet Union. British police are reportedly working from the theory that the nerve agent was somehow stowed in Yulia's luggage when she came to visit her father from Russia.
Moscow has now opened their own investigation into the attack on Yulia, who is a Russian citizen, and they've also opened a parallel inquiry into the death of this Russian businessman. Nikolai Glushkov was found dead in his London home on Tuesday. Britain's Scotland Yard opened a murder investigation into Glushkov, a critic of Putin who they say appears to have been killed by compression to the neck.
Although they say they do not see a link to the death of the spy.
