India: New Delhi heatwave declared 'severe' as record-breaking temperatures cause children to faint
India's capital New Delhi has endured sweltering conditions in a record-breaking heatwave, which has seen temperatures reach as high as 52.3C (126.1F).
The extreme weather has been ongoing for weeks and has been affecting the northwest, central and eastern areas of the country.
The heatwave has now been classed as "severe" - meaning temperatures are at least 6.5C above average.
Pupils in government schools in the eastern state of Bihar have been fainting because of the weather, news agency ANI reported.
One girl could be seen being fanned and sprinkled with water as she lay on a classroom bench in the blistering temperatures.
"Electrolyte imbalance is causing fainting, vomiting, and dizziness," said Rajnikanth Kumar, a doctor at the hospital treating the students.
India and other parts of South Asia - and South East Asia - have been grappling with heatwaves since last month.
According to weather officials, however, temperatures are likely to ease from Thursday over northwest and central India.
