Ukraine has unleashed one of its heaviest drone bombardments of Russia, launching over 660 drones in a single night aimed at various strategic sites, including oil refineries in Moscow and Crimea. This assault comes amidst escalating tensions, as Moscow struggles to defend against these attacks, which are described as a message to the Russian population that the war is now reaching their homes. Reports indicate that the assault has caused significant damage to key infrastructure, including an oil refinery that may not resume production this year. In response, Russia has admitted to downing a substantial number of Ukrainian drones but insists that it is not seeking military assistance from Belarus. The ongoing drone strikes have raised questions about the effectiveness of Russian air defenses and the changing dynamics of the conflict, with President Zelenskyy emphasizing the need to raise the cost of war for Russia and disrupt its military operations.
