Russia launched a massive overnight drone assault on Ukraine, plunging parts of Odesa into darkness as critical infrastructure came under sustained fire. Nearly 100 UAVs were deployed in what Kyiv describes as a winter pressure campaign aimed at energy, ports and logistics hubs. As air defences scrambled and blackouts spread across southern Ukraine, a shocking twist followed inside Russia. Just hours later, an explosion ripped through Moscow, killing a senior military officer in a targeted car bombing. Investigators are probing possible links as tensions spike on both sides of the war.
