Over half a million residents throughout Ukraine lost electricity after a major Russian assault hit energy sites and other vital infrastructure during the night, President Volodymyr Zelensky posted on X on Monday.

Another Russian ballistic missile attack came in several waves overnight, and once again, there was no early warning from our partners, Zelensky wrote. They again targeted energy facilities and infrastructure, but a medical clinic, a school, a metro station, and ordinary residential buildings were also damaged.

In this one night alone, more than 10 energy infrastructure facilities were damaged, and the lights went out for at least 550,000 families. Repair crews are working at the sites.

Zelensky added that Russia had launched 16 ballistic missiles and more than 200 drones of various types, including jet-powered Shahed drones.

Unfortunately, there are casualties, he stated, sending condolences to their families.

Ukraine never wanted war, responded positively to peace attempts

Ukraine never wanted this war, and we responded positively to literally every attempt by our partners to end this war honorably to every ceasefire proposal, our answer was positive, Zelensky continued. Ballistics, Shaheds, and killings are, again and again, Russia's responses.

Putin does not want not only an end to this war, but even any de-escalatory steps. Every one of our partners has faced this personally when hearing refusals from Russia. And it is very important to call things by their proper names. To call the aggressor an aggressor and to help Ukraine protect lives.

Earlier in the day, the Russian Defense Ministry said on Monday its forces had carried out a massive strike on targets in Kyiv and Ukraine's capital region, targeting military-industrial facilities, storage sites for cruise missiles and drones, and data centers.
