BBC: An intense heatwave is sweeping through northern India with temperatures hitting a record 49.2C (120.5F) in parts of the capital, Delhi.

This is the fifth heatwave in the capital since March.

While heatwaves are common in India, especially in May and June, summer began early this year with high temperatures from March, when the first heatwave arrived.

Average maximum temperatures for the month were the highest in 122 years.

49.2C! We're clearly in a combat phase - some of the conditions cropping up are not compatible with human habitation.
