Cold weather has killed 37 people in Ukraine so far this month as temperatures reached minus 23 Celsius in parts of the former Soviet republic. Night temperatures are expected to drop to -28C in northern, central and eastern Ukraine this week. The cold snap followed heavy snowfall which left some areas covered with as much as 53 cm (21 inches) of snow. Cars were blocked for 18 kilometres (11 miles) overnight on Saturday on the main road between the capital Kyiv and Lviv, officials said.
