Large parts of India, including national capital New Delhi, have endured days of sweltering heat, prompting fears of power cuts. But the highest temperatures have been recorded in Telangana and neighbouring Andhra Pradesh state.
Andhra Pradesh authorities are urging labourers and others not to work long hours in the heat of the day after 246 people died from the high temperatures there in the last week.
"The majority of the victims are people who have been exposed to the sun directly, usually aged 50 and above and from the working classes," P. Tulsi Rani, special commissioner of Andhra Pradesh's disaster management department, told AFP.
