Thousands of people, including children and the elderly, were trapped in water-logged homes in Hanoi on Tuesday. Twenty people have died in the city since Friday and 44 neighbourhoods remain under water that is up to 2.5 metres high.
Officials say that 9,000 troops have joined rescue efforts but residents in many areas say that they are still waiting for help. Hospitals are packed with cases of respiratory and gastrointestinal diseases, while there are fears that cholera and dengue fever may break out.
Officials say that rain-soaked dykes around Hanoi and in the northern Red River delta could burst and they have deployed thousands of troops in those areas.

Across the region, more than 120,000 buildings have been flooded, according to official figures, while 250,000 hectares of rice and other crops have been lost.
