At least 21 people have been killed over the weekend in one of Poland’s deadliest-ever cold snaps, with temperatures falling to -0.4F, officials say.
Since November 1, 2015, at least 39 people have been killed by cold weather in Poland.
Meanwhile in the German city of Bremen 300 refugees were reportedly evacuated from tents.
Since the New Year freezing temperatures have made conditions even more difficult for migrants living in temporary accommodation.
The water supply and heating to the tents in Bremen had stopped working, officials told the Neue Osnabrucker Zeitung newspaper.
Other German media said refugees waiting to be registered as refugees were standing in freezing temperatures outside government offices in Berlin, which have reopened after the holidays.
