BY A STAFF REPORTER: Russian forces struck Ukraine's southern Zaporizhzhia city and the northeastern Kharkiv region with dozens of missiles overnight into Friday, according to the Ukrainian Air Force. “The enemy attacked Kharkiv region and Zaporizhzhia region with up to 35 S-300 surface-to-air missiles that cannot be destroyed in the air with the air defense," the Ukrainian Air Force said. The Soviet-era S-300, designed to take down combat aircraft, has been crudely repurposed by Russia to hit ground targets during its war on Ukraine. Russian forces also fired C-300 surface-to-air missiles from across the border in Belgorod and from the occupied city of Tokmak in southern Ukraine, the air force added.
