Frigid temperatures have gripped Europe in the last week, with the mercury reaching as low as 35 degrees Celsius below zero. After what had been a relatively mild winter, the sudden cold caught many unprepared. Eastern Europe is hardest hit, with over 100 deaths in Ukraine, and with over 11,000 people in remote villages cut off by snow in Serbia. Most of the fatalities recorded have been homeless people found frozen to death outside, and emergency tents with hot meals have been set up to help them in several affected countries. Russia and Poland are mobilizing help for the homeless. Travel in Romania has been chaos as a blizzard hampered efforts to clear both rails and roads. Recorded temperatures in Italy were the lowest in 27 years. -- Lane Turner ( 45 photos total
