Dozens were injured in a “savage” Russian drone strike Saturday on a Ukrainian railway station, Ukrainian President Volodymyr Zelenskyy said, as Moscow stepped up strikes on Ukraine’s rail and power grids ahead of the fourth winter since its all-out invasion. The head of Chernihiv’s military administration, Dmytro Bryzhynskyi, confirmed a nighttime Russian attack on the city caused multiple fires, but did not immediately say what was hit. Overnight into Saturday, Russian forces launched a further 109 drones and three ballistic missiles at Ukraine, the Ukrainian military reported. Since Russia’s February 2022 invasion of its neighbor, each year as winter approaches Russian forces have blasted Ukraine’s power grid. Russia has recently escalated its strikes on Ukraine’s power grid, as well as its rail network, which is essential for military transport.
