Sergey Lavrov spoke in response to the British government’s demand for an explanation of the use of a military-grade nerve agent produced in Russia in the attack in the English city of Salisbury.
Lavrov told reporters on Tuesday Moscow’s requests to see samples of the nerve agent have been turned down, which he called a violation of the Chemical Weapons Convention, which outlaws the production of chemical weapons. He insisted that Russia is "not to blame" for the poisoning.
He said Moscow is willing to cooperate with the probe but suggested that London would be "better off" complying with its international obligations "before putting forward ultimatums."
Russian news agencies reported that the Foreign Ministry has summoned the British ambassador in Moscow over the poisoning.
British Prime Minister Theresa May said Russia’s involvement is "highly likely" and delivered a Tuesday deadline for a Russian response.
Officials said Tuesday Prime Minister Theresa May is reviewing a range of economic and diplomatic measures in retaliation for the assault with a military-grade nerve agent. -- AP
