Saturday was the hottest day this year in Karachi, where the mercury had shot up to 45 degree Celsius, Dawn online reported.
The maximum temperature of 48 degree Celsius was recorded in three districts of Sindh - Jacobabad, Larkana and Sukkur - on Saturday, which slid down to 41 on Sunday.
According to health officials, many patients complained that they had collapsed suddenly during the day and suffered extreme breathing problem.
The process of burying bodies has been expedited as the number of bodies arriving in morgues had suddenly swollen and also because the temperatures were too high for the cooling facility, the officials added.
The highest temperature Karachi ever experienced was 48 degree Celsius on May 9, 1938.
