A severe heatwave continues to wreak havoc in India as the eastern state of Odisha on Monday reported eight deaths within a 72-hour period.

Official figures released in May suggested 60 people died between March and May across India due to heat-related illnesses.

But the number is likely to be much higher as heat-related deaths go under-reported in rural areas.

Officials say India is in the middle of the longest heatwave it has seen since records began. Temperatures have crossed 50C in some areas recently.
