Morgues have been filling up and hospitals struggling to cope in southern Pakistan which has been struck by an intense heatwave.<br /><br /> The authorities said on Tuesday that more than 400 people had been killed in Karachi alone over a three-day period.<br /><br /> Amid soaring temperatures of well over 40 degrees Celsius, the electricity grid crashed over the weekend causing power cuts that left millions of people without water, air-conditioning, fans and light.<br /><br /> “There’s no way of knowing when the power will come back on. Everything is going wrong because of the power cuts. I just saw a dead body; the family told me the father had died because there was no ambulance available,” said Karachi resident Zobair Ali.<br /><br /> The outages, often caused by corruption and mismanagement, have caused anger and led to demands for compensation.<br /><br /> The heatwave coincides with the first few days of Ramadan when Muslims fast during daylight hours.
