Governments issue health warnings as schools shut and crops fail, with fears that worse is to come as heatwave tightens grip
Extreme heat has gripped much of south and south-east Asia over recent weeks, killing dozens of people, forcing millions of students to miss school and destroying crops.
Both the Philippines and Bangladesh shut schools due to the unbearable heat last month, while governments across the region have issued health warnings. In Thailand, at least 30 people have died from heatstroke since the start of the year.
