A series of long-range Ukrainian attacks hit targets deep inside Russia on Wednesday, part of Kyiv’s efforts to raise the costs of the war for the Kremlin by striking energy facilities and military industries. President Volodymyr Zelenskyy said Ukrainian forces struck several military and energy infrastructure sites, including a military factory.

Russia said it downed 326 Ukrainian drones overnight. The Astra online news outlet reported that a Ukrainian strike hit the VNIIR-Progress plant that produces antennas for drones. Zelenskyy also said Ukrainian forces struck a refinery in Russia’s Samara region.
