 Lavrov threatens Ukraine. Russia will respond to drone attack on Kremlin with concrete steps. Moscow will respond to Kiev's attempt to attack the Kremlin with drones not with speculations, but with concrete action. Russian Foreign Minister Sergei Lavrov said after a meeting of the Council of Foreign Ministers of the Shanghai Cooperation Organization member states. Asked by journalists whether such a term of Roman laws, Casus Belli, was applicable to this incident, Lavrov suggested avoiding picking any terms. It was obviously a hostile act. It is absolutely clear that without the knowledge of their patrons the terrorists in Kiev could not have committed it. We will respond not with speculations about whether or not this is a Casus Belli. We will respond with concrete actions. Lavrov dwelt separately on Washington's attitude toward what was happening and drew attention to US Secretary of State Antony Blinken's remarks. He said that the US will not dictate to Ukraine the methods of defending its sovereignty. I guess this says it all, Lavrov pointed out.
