A child grabs her mother's scarf as they are both covered with a water-soaked towel, to beat the heat, in Karachi, Pakistan, June 24, 2015. Pakistan's financial capital of Karachi is wilting in a 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.
