A man, suffering from frostbite, receives medical aid inside an ambulance during a charity event held by social movements and the Russian Orthodox church to help homeless people in the southern city of Stavropol, February 2, 2012. The air temperature was about minus 15 degrees Celsius (5 degrees Fahrenheit). Record-low temperatures in parts of Eastern Europe pushed the death toll from Arctic conditions to at least 89 people on Wednesday, and have forced Russian gas provider Gazprom to warn over supplies to Europe.
