"Even in case of war, not speaking of other more peaceful situations like the current one. The intentions of the US authorities and possible follow-up measures in relation to the searches of the premises of Consulate General are a clear, flagrant and unprecedented violation of the 1961 Vienna Convention on Diplomatic Relations," Kosachev wrote on Facebook.
The senior lawmaker stressed that the convention clearly states that even in case of war, diplomatic immunity is preserved up until the moment when members of the diplomatic staff leave the foreign country.
"Leaving behind the brackets the political and legal incompetence of the decision on the closure, I strongly oppose the right to enter the working and living premises of the consulate with reference to the fact that it no longer functions," Kosachev concluded.
Earlier in the day, Russian Foreign Ministry said that Moscow resolutely opposes Washington's latest decision to shut several Russian diplomatic compounds in the United States and reserves the right of retaliatory measures.
