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. Officials in many parts of the country have asked people to take precautions as temperatures are set to remain high. They warned the heat could cause health concerns for the vulnerable, including infants, the elderly and people with chronic diseases. The states of Himachal Pradesh, Haryana, Uttarakhand, Punjab, and Bihar have particularly witnessed soaring temperatures in the past few days, India's weather department said. It added that temperatures are likely to fall by 2-4C in some areas but there may not be any respite from intense heat.
