May says Russia ‘highly likely’ behind ex-spy’s poisoning

LONDON » Russia is “highly likely” to blame for poisoning a former spy and his daughter with a militarygrade nerve agent, British Prime Minister Theresa May said Monday, demanding that Moscow give a compelling explanation or face “extensive” retaliation.

May told lawmakers that without a credible response from Russia by the end of Tuesday, Britain would consider the attack on Sergei Skripal and his daughter “an unlawful use of force by the Russian state against the United Kingdom.”

“There can be no question of business as usual with Russia,” she said, without saying what measures Britain might take.

Russian Foreign Ministry spokeswoman Maria Zakharova dismissed May’s allegations as a “circus show in the British Parliament.”

Skripal, 66, and his 33-year-old daughter, Yulia, remain in critical condition after being found unconscious March 4 in Salisbury.
