Scores of people are still being evacuated from their homes in the Czech Republic as flooding continues to hit central Europe.Heavy rain and rapidly melting snow have led to alerts in Germany, Hungary, Slovakia and Romania. So far at least five people have died. A state of emergency has been declared in some parts of the Czech Republic and the historic city of Olomouc was flooded overnight when a dyke was breached. There are also high alerts further north with the Elbe river still rising. People have been evacuated from their homes along the river from villages near Prague to Dresden in Germany. In worst affected areas people have been busy building up dykes and defences with sandbags, while trying to pump out floodwaters. For many though they can only pray the river levels do not rise any further.
