Ukrainian officials on Sunday accused Russia of causing electric blackouts across much of eastern Ukraine, as the country's military prepares to take back some of the territory it lost to the Russians.
President Volodymyr Zelensky accused Russian forces of trying to "deprive people of light and heat" in a Sunday statement.
A strike on an infrastructure facility in the city of Kharkiv left many people without power and water, according to the mayor.
Since the beginning of the month, the Ukrainian military said it had reclaimed more than 1,000 square miles of previously Russian-held territory in the eastern part of the country.
In the northern part of the Kharkiv region, which borders Russia, as well as to the south and east, the commander in chief of the Ukrainian army said.
The last reactor at the Zaporizhzhia nuclear power plant was shut down on Sunday in order to prevent a disaster. The plant only has enough diesel fuel for 10 days because of the damage to the transmission lines, and operators may have to use emergency diesel generators. There are concerns that fighting near the plant could cause a catastrophe. Zelensky and the International Atomic Energy Agency have both advocated for a demilitarized zone near the facility.
One of the biggest victories for the country may have been the retaking of territory by the Ukrainians in the Russian-controlled parts of Kharkiv. Russia acknowledged Saturday that it had retreated from Izyum and Balakliia, two key locations for its forces in the north, in order to regroup. More than $2 billion in assistance to Ukraine and its allies was announced by the U.S. this week. During his visit to Kyiv, Secretary of State Antony Blinken said that the Ukrainian military efforts had been effective against Russia. Ukrainians will continue to be supported until they are fully independent.
The reactor at Zaporizhzhia stopped working.
The Ukrainians blame Russia for the power cuts.
