A total of 223 people have died from the cold weather in the last seven days according to a foreign news agency tally, with Ukraine suffering the heaviest toll. People have been found dead on the streets in some countries, while thousands have been trapped in mountain villages in Serbia. In Italy, Venice's canals started freezing over and even Rome was dusted in snow. The lowest temperatures recorded in Europe were in the southwest of the Czech Republic, where the mercury dropped as low as minus 38.1 degrees Celsius overnight Thursday. The EU executive said Friday that vital Russian gas deliveries had dropped in nine countries, with Russian giant Gazprom invoking flexibility clauses as it also braves a cold snap. Supplies fell 30% in Austria and 24% in Italy. Ukraine's emergencies ministry raised its death toll to 101 since the cold snap took hold, 64 of whom died on the streets.
