A Pakistani official says the devastating weeklong heat wave in the southern port city of Karachi has killed 1,233 people.

Nazar Mohammad Bozdar, operations director at the Provincial Disaster Management Authority, said Saturday that 65,000 heatstroke patients were treated at the city's hospitals since June 20 when the heat wave struck Sindh province and its capital, Karachi.

He told The Associated Press that 1,923 patients with heat-related ailments are still being treated.

Although temperatures in Karachi on Saturday came down to 34 degrees Celsius (93 degrees Fahrenheit) after touching 45 degree Celsius (113 degrees Fahrenheit) a week ago amid chronic power outages.

The heat wave struck Karachi at a time when the city's Muslim majority was observing the dawn-to-dusk fasting month of Ramadan.
