In pictures: India's heat wave

India has been sweltering under a heat wave for more than a week, with the worst hit state, Andhra Pradesh, reporting that at least 620 people have been killed by heat-related illnesses.

Forecasters say the high temperatures could continue, with hot winds blowing in from Rajasthan.

Both animals and humans have been finding the heat difficult to bear

The children who pull carts in the slums of New Delhi opted for sleeping through the heat

As did the rickshaw drivers

The battle to stay cool is ongoing

And for some it has proved too much, hundreds are being treated for heat-related illnesses

But for men dealing in second-hand fan parts the heat means big business

The same is true of the water melon vendors
