 Kiev's drone attack on the Kremlin has left Russia with no options other than the physical elimination of Ukrainian President Vladimir Zelensky and his clique. The deputy chairman of Russia's Security Council, Dmitry Madrudev said on his telegram channel. In a comment on Kiev's action, Madrudev wrote, after terrorist attack, there are no options left other than the physical elimination of Zelensky and his clique. Ukrainian President Vladimir Zelensky, according to Madrudev, is not even needed for signing an instrument of unconditional surrender. Hitler, as is known, did not sign it either. There will always be some substitute, Madrudev wrote. Russia will respond to Ukraine's acts of terrorism in the form of an attempted drone attack on the Kremlin when it deems necessary. Russian Ambassador to the United States Anatoly Antonov said, Russia will respond to this insolent and presumptuous terrorist attack. We will answer when we consider it necessary. We will answer in accordance with the assessments of the threat that Kiev posed to the leadership of our country.
