Another sleepless night for Ukraine.
Russian strikes pounded cities from Kyiv to Kharkiv overnight, killing civilians in Sumy and Zaporizhzhia, wounding dozens and triggering internet outages across the country. In the capital, air raid sirens sounded five times before 10 a.m.
Ukraine responded in kind, with long-range strikes on a major Russian oil refinery and a military plant in the Rostov region.
