Ukrainian President Volodymyr Zelensky said Russia targeted energy infrastructure and residential areas across eight regions, injuring at least 26 people. Ukrainian air defences intercepted most aerial threats, but ballistic missiles and drones still caused fires and structural damage in Kyiv, Kharkiv, Zaporizhzhia and Odesa. A substation strike left 32,000 households without power. Polish and allied aircraft patrolled nearby airspace as explosions echoed across the capital. The attack comes days after peace talks in Geneva, highlighting the fragile state of negotiations.
