“We have no right to relax, we still need to go the way to the Ukrainian victory.

And this is a difficult path - to go through this winter, which will be the most difficult in our history, ”he said in a video message on Telegram.

Earlier, the head of Naftogaz, Yuriy Vitrenko, in an interview with the German newspaper Handelsblatt, called the upcoming winter "the worst in the history of Ukraine", as serious problems with electricity and heating are expected.

According to Ukrenergo, the attacks on Ukraine's infrastructure on October 22 may have caused more damage than previous attacks.

Zelensky urged city mayors to monitor the amount of electricity consumed.
