The Kremlin says it will respond appropriately to the United States’ expulsion of 60 Russian diplomats and closure of the Russian consulate located in Seattle.

The Russian Foreign Ministry on Tuesday said that not a single country has been able to provide evidence that Russia was behind the poisoning of former Russian spy, Sergei Skripal and his daughter, Yulia in Salisbury, the United Kingdom.

The United States had on Monday said it would expel 60 Russian diplomats, joining governments across Europe in punishing the Kremlin for the nerve agent attack which they blamed on Moscow.
