Tens of millions of people have been left homeless and scores killed in the worst flooding to hit southern Asia in a decade. More than half of Bangladesh is said to be under water after weeks of unrelenting rain. Bangladesh is accustomed to flooding with the arrival of the monsoon season. But conditions this year are particularly severe. Entire communities have been cut off and millions are in desperate need of food and essential supplies. There is a similar situation in northern India. In one of the worst incidents a boat capsized killing 28 people, including 12 children. The apparently slow response of authorities has enraged those in the affected region. There have been reports of looting in two Indian states as people take matters their own hands. The annual monsoon deluge is vital to the subcontinent’s economy and agricultural, but this year it has caused major devastation to both.
