Russian spy: Highly Likely Moscow Behind Attack, Says Theresa May

Former spy Sergei Skripal and his daughter were poisoned by a military-grade nerve agent of a type developed by Russia, Theresa May has told MPs, according to BBC. 

The PM said it was "highly likely" Russia was responsible for the Salisbury attack.

The Foreign Office summoned Russia's ambassador to provide an explanation.
