Dozens of migrants are at risk of freezing to death in Europe after heavy snowfall and bitterly cold temperatures hit Greece and the Balkans, aid agencies said on Wednesday.
Central and Southeastern Europe have been gripped by freezing weather and snowstorms for days, with night-time temperatures dropping below minus 20 degrees Celsius (minus 4 Fahrenheit) in some areas.
The Missing Migrants Project, set up by the U.N. migration agency (IOM), has recorded 11 migrants deaths in the Mediterranean since the start of the year, including four who died of hypothermia at Europe's land borders with Turkey.
