Russian forces have resumed attacking Kyiv and western Ukraine.
It follows the loss of the Russian Black Sea flagship Moskva and alleged Ukrainian strikes on Russian territory.
The Russian military command had warned of renewed attacks on Ukraine's capital and said it was attacking military sites.
A spokesman for Russia's Defence Ministry said forces used "air-launched high-precision long-range weapons" to target an armoured vehicle plant in Kyiv.
Another strike hit a missile plant on Friday, after Russian troops failed to capture the city and withdrew to concentrate on launching a full-scale assault in eastern Ukraine.
In the eastern city of Kharkiv, Associated Press reporters documented civilian deaths in strikes this week.
Firefighters said an explosion, believed to be caused by a missile, struck Ukraine's second-largest city.
The strike near an outdoor market killed one person and wounded at least 18, rescue workers said.
Ukrainian President Volodymyr Zelensky accused Russian troops occupying parts of the Kherson and Zaporizhzhia regions in the south of terrorising civilians and hunting for anyone who served in Ukraine's military or government.
"The occupiers think this will make it easier for them to control this territory. But they are very wrong. They are fooling themselves," Mr Zelensky said in his nightly video address.
"Russia's problem is that it is not accepted — and never will be accepted — by the entire Ukrainian people. Russia has lost Ukraine forever."
Officials think 2,500 to 3,000 Ukrainian troops have died in the war, Mr Zelenskyy told CNN in an interview. He said about 10,000 have been injured and it is "hard to say how many will survive".
The United Nations' human rights office said it has confirmed the deaths of 1,982 civilians but cautioned that the figure does not include people killed in blockaded cities like Mariupol, so the actual number is almost sure to be considerably higher.
