Twelve people froze to death in Poland overnight, bringing the country's overall death toll caused by harsh weather in the past three days to 30.
Severe frost also left some 150,000 people in the southern Polish city of Czestochowa without heating early today. Officials are trying to fix the problem.
Heavy snow and sub-zero temperatures are causing travel chaos in many north European countries, with some airports closed and rail and road traffic badly disrupted.
