Zelenskyy wrote about this on Telegram.He reported that 15 regions of Ukraine came under Russian attack. Russia deployed 415 drones of various types and over 40 cruise and ballistic missiles. At the same time, several drones crossed into Polish airspace.“Moscow always pushes the boundaries of what is possible, and if it does not encounter a strong reaction, it remains at the new level of escalation. Today there was another step of escalation – Russian-Iranian “shaheds” operated in the airspace of Poland, in NATO airspace. It was not just one 'shahed' that could be called an accident, but at least eight strike drones aimed toward Poland,” the statement said.The president emphasized that this is an extremely dangerous precedent for Europe.“Whether there will be further steps depends entirely on the coordination and strength of the response. The Russians must feel the consequences. Russia must feel that the war cannot be expanded and will have to be ended. The pause in sanctions has gone on far too long. Delaying restrictions on Russia and its accomplices only means increasing the brutality of the strikes. Sufficient weapons are needed to deter Russia. A strong response is needed – and it can only be a joint response by all partners: Ukraine, Poland, all Europeans, the United States. I thank everyone who is helping,” Zelenskyy stressed.On September 10, Polish Armed Forces’ Operational Command put air defense systems and aviation on highest alert due to Russia’s night attack on Ukraine: Russian drones violated the country’s airspace.
