The Czech capital Prague declared a state of emergency as the worst flooding for more than a decade tore into the city, threatening to engulf the streets of its historic heart.
Supported by troops and volunteers, Prague's fire brigade erected metal flood barriers and sandbag walls in a battle to keep the River Vltava at bay while the city zoo's tigers were tranquillised as part of an animal exodus to the safety of dry ground.
Schools were closed, much of the Prague transport system shut down and the famous Charles Bridge spanning the Vltava, usually jammed with tourists, was closed.
Days of torrential rain have hit central Europe and turned placid rivers into raging, muddy torrents that have claimed the lives of eight people and destroyed scores of buildings across the Czech Republic, southern Germany and Austria. Nine people are missing.
In the Czech Republic, more than 7000 people have been evacuated. Petr Necas, the Czech Prime Minister, said he had ordered the release of emergency funding for people who had lost their homes to the flooding.
