Rescue agencies and governments are rushing food and first aid to millions of people left stranded by severe flooding in south Asia. In Vietnam, dozens of people have been killed and many more have been left without food and clean drinking water. There are also fears of epidemics with the spread of water-borne diseases. Rescue efforts have been hampered by serious damage to the roads. All north-south trains have been cancelled as many sections of track have been damaged. The whole of the region is suffering from unusually severe flooding with this year’s exceptional monsoon rains. Bangladesh is also struggling to contain outbreaks of disease as waters start receding. Nearly half the country was under water. In neighbouring India, more than 1,400 people are thought to have been killed since the start of the monsoon in June.
