Since the successive setbacks on the battlefield in summer and autumn, the Russian army has continued to attack key infrastructure in various parts of Ukraine with missiles and drones, causing millions of Ukrainians to be frozen and dark in the cold winter.

Ukrainian power companies have been forced into rolling blackouts for the past few weeks, and Moscow targeted energy infrastructure last week to mount an attack on Ukraine's grid, adding to the load on Ukraine's grid.

Ukrainian Prime Minister Denys Shmygal said this week that the Russian attack caused 40 to 50 percent of the power grid to fail.

In the film yesterday, Zelensky urgently appealed to some 70 countries and international organizations participating in a meeting in Paris, France, to help Ukraine withstand the Russian winter offensive.

He said that Ukraine's energy sector, which has been paralyzed, needs about 800 million euros in the short term, emphasizing that Ukraine needs spare parts for repairs, high-power generators, additional natural gas supplies and increased electricity imports.

Ukrainian Foreign Minister Dmytro Kuleba also called on allies to provide more weapons to help Ukraine "survive the winter" and keep Kyiv's military gains alive.
