Russia launched overnight ballistic missile and drone attacks on Kyiv and several Ukrainian regions, killing at least six people, including a nine-year-old child, and injuring dozens, Ukrainian officials said. The barrage came after President Volodymyr Zelenskiy warned of intensified attacks, while Moscow said Ukrainian drone strikes also killed four civilians in the Russian-occupied city of Horlivka. The renewed exchanges underscored the continued escalation of the more than four-year-old war, with both sides accusing each other of targeting civilians.
