Heavy rainfall has sparked severe flooding across large parts of Eastern Europe. In Serbia, more than four months average of rain fell on Wednesday forcing authorities to declare a nationwide state of emergency. At least one firefighter was killed during a rescue operation on the Jasenica River. The body of another man was recovered from the Danube in Novi Sad. Several Bosnian cities have also been badly affected by floods caused by what is thought to be the heaviest rains of the past century. Dozens of people have been evacuated from their homes with the Bosna river swollen to record levels. In many areas, the strength of the tide has washed away bridges and buildings. Hungary’s Lake Balaton has also been affected. With water levels exceeding one metre, authorities have appealed to those who can to help widespread emergency efforts.
