“This is impossible,” Naryshkin told TASS, commenting on Kyiv’s statements about its intentions to work on the “return of Crimea.”

Earlier, the chairman of the Public Chamber of Crimea, Alexander Formanchuk, said that Kyiv's plan to seize the peninsula with weapons in hand is tantamount to suicide.

The intention of Kyiv to return the Crimea under the control of Ukraine was announced by the head of the Main Directorate of Intelligence of the Ministry of Defense of Ukraine Kirill Budanov.

Crimea became a Russian region after a referendum held there in March 2014: the majority of residents voted for reunification with Russia.
