More Extreme Weather

BBC:

Almost 20 million people have been displaced as some of the worst floods for years have hit a wide swathe of northern India, Bangladesh and Nepal.

Roads have been washed away and hundreds of villages have been cut off by swollen rivers.

A BBC correspondent in the Indian state of Assam says the air force is organising food drops, but they are nowhere near enough.

It's been raining for 20 days.
