ISLAMABAD (AP) — Doctors treated hundreds of victims of heatstroke at hospitals across Pakistan on Thursday after an intense heatwave sent temperatures above normal levels due to climate change, officials said.

Temperatures soared as high as 49 degrees Celsius (120 degrees Fahrenheit) the previous day in Mohenjo Daro. The city, known for its archaeological sites, is in southern Sindh province, which was badly hit by climate-induced monsoon rains and devastating floods in 2022. The heatwave is forecast to continue for at least a week.

Authorities have urged people to stay indoors, hydrate and avoid unnecessary travel. But laborers say they don’t have a choice because they need to work to feed their families.
