Work is continuing across much of central Europe to shore up flood defences. In the Czech Republic, rivers across the region have swollen due to melted snow and heavy rain, forcing more residents to evacuate and bringing businesses to a halt. The government has declared a state of emergency in seven of its 14 regions after seven flood-related deaths were reported. Unlike 2002, the ancient capital of Prague has been spared any serious damage, however it remains on high alert amid fears the situation may worsen.On Sunday night a dam burst on the March river, which separates Austria from Slovakia, flooding the Austrian village of Duernkrut. Around 200 people had to be airlifted to safety as water levels in the village approached two metres. With the water flowing north, the River Elbe in Germany rose further overnight, but not as quickly as had been feared. Workers have been toiling around the clock checking dikes, building barriers of sandbags and pumping water away. Authorities in the eastern state of Saxony, the worst affected region in Germany, expected the flood to reach its high point tomorrow.
