India, Nepal and Bangladesh are battling some of the worst monsoon rains in recent history, which have left around 1,200 people dead and 41 million people affected. In India more than 32 million people have reportedly been impacted by downpours.

Vast areas of land across all three countries are underwater, according to the Red Cross. “Rainwater from the Himalayas is travelling down through Nepal’s lower-lying areas, through swollen rivers in north-east India and eventually through the floodplains of Bangladesh,” it said in a statement.

West Bengal is the worst affected area in India, with 152 deaths and 15 million people affected, according to the UN. The country is struggling to deal with heavier-than-usual monsoon rains, with more than 600 deaths caused by downpours.

Floods in Mumbai have prompted locals to open their homes to those stranded, using the hashtag “Rainhost.”
