Ukrainian attacks across Russia and annexed Crimea killed at least three people, authorities said Wednesday morning, as Ukrainian President Volodymyr Zelensky claimed his military struck several industrial sites in an overnight blitz. In a post on X, Zelensky said long-range attacks targeted an oil refinery and logistics center in the central Ryazan region. He said an oil refinery in the Perm region was also hit, as well as an export terminal and defense enterprise in the southern Rostov region. Authorities in the Ryazan region confirmed that several industrial sites caught fire amid attacks in the capital city, adding that six people sought medical attention. Taganrog, located in the Rostov region, is home to industrial plants and a major grain export terminal.
