Dozens of people were rescued from snow-blocked villages in Serbia and Bosnia after a sever cold spell hit Eastern Europe, the Associated Press said.
Food and medicine were air-lifted into the area as the death toll rose to 83 on Wednesday. Emergency crews worked overtime in freezing temperatures to help dozens of stranded people.
In Bulgaria, 16 towns recorded their lowest temperatures since records started nearly 100 years ago.
Some Bosnian villages have had no power or electricity for days, and crews were working long hours to help restore power in the area.
