U.K. Prime Minister Theresa May on Monday said it was “highly likely” that Russia was to blame for the poisoning of a former Russian spy, who along with his daughter were poisoned by a military-grade nerve agent.
The spy was murdered on 4 March near his home in southern England.
“It is now clear that Mr. Skripal and his daughter were poisoned with a military-grade nerve agent of a type developed by Russia,” May said.
“The government has concluded that it is highly likely that Russia was responsible for the act against Sergei and Yulia Skripal, she added.
May said Russia’s ambassador in London had been issued with summons to explain whether it was was “a direct action by the Russian state” or the result of it “losing control” of its stock of nerve agents. She said a response was expected from Russia by the end of Tuesday
The PM made the remarks in an address to Parliament.
“Should there be no credible response, we will conclude that this action amounts to an unlawful use of force by the Russian state against the United Kingdom, and I will come back to this House and set out the full range of measures we will take in response,” May added.
