The assault on energy infrastructure, a significant theater in the war, followed a large-scale Russian drone attack on Kyiv.

In early November, drone video surfaced online, appearing to show a targeted strike blowing up three antennas on the roof of an apartment block. The Ukrainian drone commander who posted it claimed to have destroyed a Russian Pole-21 electronic warfare system on the eastern front near Donetsk.

Storms have battered southern and eastern Ukraine, as well as parts of Russia, reportedly hampering Moscow’s campaign around Avdiivka.

Russian forces were ramping up attacks in eastern Ukraine on Moscow and Kyiv said, as they vie to secure elusive territorial gains before the end of the year.
