A severe heatwave continued to batter Pakistan’s largest city of Karachi for a third week, filling hospitals with patients and morgues with bodies, officials and rescuers said on July 4. More than 50 people have died so far due to heatstroke since the start of the latest wave last month, police spokeswoman Summiya Syed said. Dozens of new victims were brought to the city’s largest Jinnah Postgraduate Medical Centre on July 3, the hospital’s spokesman Hassan Ali told the dpa news agency. The heat index -- a combination of the temperature and humidity -- rose to 55 degrees Celsius on July 3, the highest level ever recorded in the coastal city of more than 20 million people, chief meteorologist Sardar Sarfraz said.
