The comments come as the U.K. defense ministry said it was "highly likely" that Russian reservists had suffered heavy casualties in Ukraine, two months after they were mobilized to fight by President Vladimir Putin.

Meantime, around 70% of Kyiv's regional government remains without electricity, the head of the regional government said.

NATO Secretary General Jens Stoltenberg said that next week at the alliance's foreign ministers meeting he will urge partners to contribute more to the defense of Ukraine.
"Yes, we are all paying a price for Russia's war against Ukraine. But the price we pay is in money. While the price Ukrainians pay is in blood. And if we let Putin win, all of us will pay a much higher price, for many years to come," Stoltenberg told reporters at NATO's headquarters in Brussels.
"So NATO will continue to stand with Ukraine for as long as it takes. We will not back down," Stoltenberg added.

'We share your pain': Putin meets with mothers of Russian soldiers
President Vladimir Putin met on Friday with the mothers of Russian soldiers fighting in Ukraine, telling them that he and his country shared their pain.
Sitting with the group of women around a table with tea and cake, Putin said he understood that nothing could replace the loss of a son.
"I would like you to know that, that I personally, and the whole leadership of the country, we share your pain," he said, according to a recorded television clip seen by Reuters.
"We understand that nothing can replace the loss of a son — especially for a mother. We share this pain," he added.
The clip did not immediately show the mothers' response to Putin's comments.
Hundreds of thousands of Russian soldiers have been sent to fight in Ukraine this year, including around 300,000 reservists who were called up in September in a "partial" mobilization.

Russian strikes throw millions into hardship, UN rights boss says
At least 77 civilians have died and millions have been plunged into extreme hardship since Russia started pounding Ukraine's critical infrastructure in October, the U.N. human rights chief said.
"Millions are being plunged into extreme hardship and appalling conditions of life by these strikes," said Volker Turk in a statement, according to Reuters.
"Taken as a whole, this raises serious problems under international humanitarian law, which requires a concrete and direct military advantage for each object attacked," he added.
Turk also noted that an early analysis of videos purporting to show Ukrainian soldiers executing Russian prisoners of war indicated they were "highly likely to be authentic."
