Rex Tillerson said the poisoning of a former Russian spy in Britain last week "clearly came from Russia" and "certainly will trigger a response."
He added that he did not know whether the Kremlin had knowledge of the March 4 attack on Sergei Skripal and his daughter Yulia. But he did say that the poison could not have originated anywhere else and was "only in the hands of a very, very limited number of parties." He did not elaborate on what response might follow.
"There is never a justification for this type of attack – the attempted murder of a private citizen on the soil of a sovereign nation – and we are outraged that Russia appears to have again engaged in such behavior," Tillerson said. "From Ukraine to Syria – and now the U.K. – Russia continues to be an irresponsible force of instability in the world, acting with open disregard for the sovereignty of other states and the life of their citizens."
Tillerson spoke hours after British Prime Minister Theresa May told the House of Commons that Moscow was "highly likely" to blame for the attack in the southwestern city of Salisbury. Tillerson's statement said that he had "full confidence in the U.K.’s investigation" and its assessment of Russian responsibility.
As it was reported earlier Theresa May, Prime Minister of the United Kingdom, said that Russia is likely to be involved in the poisoning of Sergei Skripal, a former Russian military intelligence officer. She said that in the Parliament. According to her, Skripal was poisoned by a military neuroparalytic substance, made by Russia. She believes that it was either Russia’s direct action or Moscow lost grip of its chemical weapon.
May said, that Boris Johnson, Secretary of State for Foreign and Commonwealth Affairs, on March 12 called Russian ambassador for an explanation of how the substance appeared in Salisbury and was used against former Russian military intelligence officer. London expects Russia’s respond till the evening of March 13.
