Pakistan Heat Wave, Power Failures Kill Nearly 700 in Karachi

The 23.5 million residents of Karachi have suffered through a deadly combination of high heat, extremely high humidity, and frequent power outages that disabled fans and air conditioners throughout the teeming Pakistani port city since the weekend.
The death toll is creeping toward 700, with 622 deaths reported by the AP. But heat-related deaths are often undercounted, since heat can be a contributing factor to death, but not the primary cause, in many instances.
