MOSCOW, March 16. /TASS/. Moscow has already taken decisions on response measures and will inform London about them soon, Russian Foreign Ministry Spokeswoman Maria Zakharova told TASS on Friday.
"The Russian side has taken all decisions and will inform both the British side and general public about them soon," she said.
Former Russian military intelligence (GRU) Colonel Sergei Skripal and his daughter Yulia suffered the effects of an unknown nerve agent in the British city of Salisbury on March 4. They are currently in the hospital in critical condition.
Skripal was earlier convicted in Russia of spying for Great Britain and exchanged for Russian intelligence officers.
British Prime Minister Theresa May said the substance used in the attack had been a Novichok-class nerve agent developed in the Soviet Union. On March 14, she accused Russia of an "unlawful use of force" against the United Kingdom and announced that London would expel 23 Russian diplomats and take other restrictive measures.
Russia has rejected all accusations and vowed to respond to the UK’s steps.
