At least three people died overnight to Sunday in Moscow from cold, bringing to 23 the number killed in the Russian capital by the recent Siberian weather front, where temperatures are expected to plummet again in the coming days, emergency services said, according to DPA. Temperatures in the city of 10 million hovered around a relatively mild minus 19-22 degrees Celsius Sunday after falling as low as minus 32 during the week in the coldest weather seen in the country in 25 years. Fresh lows of up to minus 30 degrees were expected for Monday and could last up to two days before rising to between minus 10 and minus 15 degrees Celsius on Wednesday, forecasters said. The unusually cold snap has claimed several dozen victims throughout Russia and wrought havoc with energy supplies.
