CALAMITY// More than 1000 people have died from a heatwave in southern Pakistan’s port city of Karachi, as medics battled to treat victims after a state of emergency is declared in hospitals. Most of them have died of heatstroke, dehydration or other heat-related illnesses as mercury touched 45 degrees Celsius recently during the holy month of Ramadan. Pakistan’s Prime Minister Nawaz Sharif called for emergency measures to be put in place. The provincial government in Sindh had declared a public holiday for schools and government offices due to the extreme heat. The government has also set up several heatstroke aid centres to battle the situation.
