A tense overnight assault has put Ukraine’s energy system under extreme pressure, as waves of drones and missiles struck while temperatures plunged to dangerous lows.

KYIV, Feb 7 (Reuters) – Russia launched more than 400 drones and about 40 missiles on Saturday to attack Ukraine’s energy sector, targeting the power grid, generation facilities, and distribution substations, President Volodymyr Zelenskiy said.

“Every day, Russia could choose real diplomacy, but it chooses new strikes,” Zelenskiy posted on X. “It is crucial that everyone who supports the trilateral negotiations respond to this. Moscow must be deprived of the ability to use the cold as leverage against Ukraine.”
