Russia hammered Ukraine with its largest air barrage of 2026 on January 11-13, launching 154 drones and missiles at Kyiv, Kharkiv, and energy grids, killing at least four civilians, injuring dozens, and triggering widespread blackouts in freezing weather. 

Ukraine struck back with drones torching Russia's Novocherkassk power plant and oil facilities in Rostov, plus a fatality in Voronezh from debris. Russian forces reported advances near Novoboikivske in Zaporizhia, while US officials decried the escalation as Ukrainian defenses hold amid Trump's incoming peace push.
