 Russian officials said a fire had broken out at a power substation in the Rostov region bordering Ukraine after overnight drone attacks. The regional governor wrote on the Telegram messaging app that Russian air defence systems had intercepted a number of Ukrainian drones. Earlier, the UN security general condemned Russia's broad missile attack on Ukraine that killed more than 40 people, including some at a children's hospital in the capital.
