'Heatwave kills at least 65' in Pakistan's Karachi

At least 65 people have died in a four-day heatwave in Pakistan's Karachi, according to a charity that runs a morgue in the city. 

Karachi, home to more than 21 million people, has seen four consecutive days with temperatures above 42C. This compares with an average mid-May maximum temperature of 37C.

Although the maximum temperature during this period reached 44.1C, it remains a long way short of the city’s May record of 48C, set in 1938.

Many fear the final death toll from this week's heatwave could be much higher as it coincides with the Muslim holy month of Ramadan, during which many Muslims fast. 

The city’s notoriously poor and erratic electricity supply is also expected to contribute to number of deaths. 

Temperatures across the region are expected to return to "normal" over the coming weekend.

The last deadly heatwave to affect Karachi and the rest of Sindh province was in April 2017.

Some 2,000 people died from dehydration and heat stroke as the area witnessed temperatures as high 49C. A similar number of deaths was reported during the heatwave of June 2015.
