Pakistan heat 'kills at least 749'
At least 749 people have been killed in a scorching heat wave in Pakistan, an official said as temperatures began to drop across the country.
Mohammad Sabir said that the city hardest hit by the intense weather was Karachi.
The port city has seen temperatures soar to 45 degrees Celsius (113 degrees Fahrenheit). Meteorologists say the heat wave is the worst in at least a decade.
Long power outages, little running water and the majority of people fasting for the Muslim holy month of Ramadan have worsened the situation.
The cooler temperatures on Wednesday appeared to be helping. Hospital officials said admittances had dropped compared to previous days, when dehydrated patients lay in corridors and outside of clinics.
