On Wednesday night 53 people died in Ukraine alone as the extreme conditions covered Athens's Acropolis in snow and froze stretches of the eastern Danube running between Bulgaria and Romania.
The week-long deep freeze, forecast to last through Thursday, has claimed hundreds of lives from the Baltic nations and Russia in the north all the way down to Turkey and Greece, both hit badly by uninterrupted snowfall.
The toll in Ukraine brings to 130 the number of weather-related deaths there since temperatures plunged into the minus 20s and minus 30s Celsius.
Ukraine's power grid has been tested to the limit, leading to record consumption of natural gas and, consequently, another row with neighbouring supplier Russia, which accused Kiev of using gas destined for its downstream European clients.
Russia deaths
In Russia itself, well over 100 deaths have been recorded in Moscow alone. In Poland 14 persons died overnight on Tuesday and 53 have succumbed since last week.
At least half of all victims are homeless people, according to official statistics, and many deaths are alcohol related.
Temporary shelters have been set up in sports gyms, public buildings and hospitals throughout Eastern Europe in an effort to get people off the street.
Twenty-seven people, six of them homeless, have died because of the cold in Romania over the last five days, according to the health ministry, which attributed most of the deaths to hypothermia.

In Bulgaria, a homeless woman was found frozen to death in Sofia, one of five deaths attributed since Monday to frigid temperatures.
Thousands more across Eastern Europe are in hospital, suffering from frostbite and various stages of hypothermia.
Three people died of cold in Serbia on Wednesday, as temperatures dropped down to minus 36 degrees Celsius, local media reported.

Snow covers Mediterranean
Especially hard hit Tuesday and Wednesday were Greece and western Turkey, unaccustomed to sustained periods of subfreezing temperatures.
Both countries were blanketed in snow and coping with massive disruptions in road, air and sea transport.
Authorities in Turkey have barely been able to keep the international airports in Istanbul and capital Ankara open, and many flights to other Turkish cities have been cancelled.
More than 800 traffic accidents have been reported in Istanbul, the commercial capital of 12 million residents, and another 300 in Ankara, resulting in 17 deaths and numerous injuries.
Sea lanes between Istanbul and nearby cities have also been shut down, and even ferry transport across the Bosphorus between the city's European and Asian sides has been disrupted.
In Greece, most ships were confined to harbor due to storm conditions in the Aegean and Ionian Seas.
In both countries thousands of villages have been cut off from road transport, and hundreds are without electricity or telephone service, while many schools and public buildings remained closed.
Authorities in Greece distributed food and blankets to 250 Gypsy and homeless families living in huts to the west of the capital.
