More than 100 people have now died as a result of freezing weather in Ukraine since last Friday, the government has announced in Kiev.
Most of the 101 who died were homeless people and 64 of them were found dead on the streets, the emergencies ministry said.
Hundreds of others have been treated in hospital for frostbite, hypothermia and other cold-related conditions.
Temperatures plunged to below -35C in parts of eastern Europe this week.
At least eight more deaths were reported in Poland on Thursday, bringing the death toll there since last week to 37.
Cold weather deaths have been reported across eastern and central Europe, and in Serbia at least 11,000 villagers have been trapped by heavy snow and blizzards in mountainous areas, the Associated Press reports.
In Ukraine, the authorities closed schools and colleges and set up nearly 3,000 heating and food shelters across the country.
Health officials instructed hospitals not to discharge homeless patients, even after treatment is finished, to save them from the cold.
Russia recorded cold 64 cold weather deaths for the whole of January, Interfax news agency reports, but it is unclear if this is related directly to the hard frosts which began last week.
