A heat wave in the Pakistani city of Karachi is blamed for over 700 deaths.
巴基斯坦城市卡拉奇遭遇高温天气，造成700多人死亡。
Intermittent power losses are also compounding the situation in the city of 20 million.
However, Pakistani forecasters are suggesting some relief may be on the way.
"Normal temperature recorded in last five days was 43 degrees centigrade but the recorded heat index in Karachi was 49 degrees centigrade, but hopefully we are expecting that some relief is expected today after the inception of sea breeze today in afternoon and some rain in the surrounding area of Karachi and within a couple of days hopefully weather will be normal in Karachi and all parts of Sindh."
The Pakistani military has set up make-shift triage centers to deal with victims, handing out free water and medical care for those affected by the sweltering heat.
