A man who suffered a frostbite lies in a hospital, with the air temperature at about minus 20 degrees Celsius (minus 4 degrees Fahrenheit) outside, in Kiev, February 1, 2012. 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. In Ukraine, 43 people have died in the past five days, its emergency ministry said, as the former Soviet republic shivered through its coldest winter in six years. Overnight temperatures sank as low as minus 33 degrees Celsius (minus 27 Fahrenheit) and hundreds of heated tents have been put up to shelter the homeless.

Van De Gevel, was ferried to the hospital at Skardu on Monday along with fellow Dutchman Wilco van Rooijen, the leader of one of the ill-fated teams involved in the worst-ever climbing disaster on K2. Eleven climbers from Europe, South Korea and Pakistan died, mostly as a result of an ice fall during their descent after summitting the 8,611 metre (28,240 foot) peak late on Friday.

Extreme cold is no surprise to the 60 million people scattered across a region wedged between Russia, China and Iran, but this year's winter has exposed the poor state of crumbling Soviet-era utilities and pipelines and sparked energy shortages.
