A policeman (L) sprinkles water on a colleague, who collapsed due to the heat, in a police van outside Jinnah Postgraduate Medical Centre (JPMC) in Karachi, Pakistan, June 24, 2015. Pakistan's financial capital of Karachi is wilting in the four-day heat wave that has killed more than 780 people, a health charity said on Wednesday, as the government declared a holiday in the city to encourage people to stay home and cool off.
