At least 65 people have been killed due to heatstroke in the last three days in Pakistan's Karachi, where the temperature hit 44 degrees Celsius, media reported on Tuesday.
At least 114 bodies were brought to the social welfare group Edhi Foundation's morgues out of which at least 65 had died from heatstroke, Xinhua news agency reported quoting the head of the foundation Faisal Edhi.
Edhi said most of the heatstroke victims had died at their home without getting any medical help on time, adding that the youngest victim was a six-year-old, while the oldest was 78.
However, health authorities in the city have denied the claim.
Pakistan Meteorological Department issued a heatwave warning for Karachi saying that the hot weather was expected to stay between 40-43 degrees in daytime throughout the week.
Local reports said that Karachi Mayor Waseem Akhtar also urged residents to stay indoors during the day to avoid heatstroke.
A severe heat wave in 2015 killed at least 1,200 people in the country.
