Death toll climbs in Karachi heatwave

Charity says at least 65 people have died in Pakistani city as temperatures exceed 40C

An intense heatwave across south Asia has killed dozens of people with sustained temperatures in excess of 40C (104F) coinciding with power cuts and Ramadan, when many Muslims avoid eating or drinking water.

At least 65 people have died in Karachi in recent days according to the charitable organisation that runs the central morgue in the Pakistani port city, as volunteers handed out water to labourers and others working outside in temperatures as high as 44C.
