 Russian officials say a fire has broken out at a power substation in the Rostov region bordering Ukraine after overnight drone attacks. The regional governor said Russian air defence systems had intercepted a number of Ukrainian drones. It comes after Russia's broad missile attack on Ukraine killed more than 30 people including children at a hospital and injured nearly 200 others. The attack was condemned by the UN Secretary General and labelled as a war crime by European Union officials. Steve Rosenberg reports on Moscow's stance.
