EUROPE’S MOST SEVERE heatwave ever has broken temperature records in eastern parts of the continent and forced Ukraine to order power cuts to cope yesterday. The extreme heat, which hit Western Europe last week, has set records in Poland, the Czech Republic and Germany as it moved east in recent days. According to the Slovak Hydrometeorological Institute, Slovakia registered a new record temperature of 41C in Turňa nad Bodvou in the southeast yesterday.
