Russia turns to new tactics to destroy Ukraine's energy grid this winter for good A barrage of explosions silenced Kyiv in the early hours of October 14 as Russia targeted several energy facilities powering the capital amid a new campaign to isolate the city ahead of winter. Deploying jet-propelled UAVs en masse alongside ballistic missiles, Moscow is adapting its tactics to strike power lines, substations and critical network connections. Energy experts warn that the strikes could also jeopardize the supply of nuclear-generated electricity. Photo: Roman Filippi / AFP via Getty Images.
