At least 230 people have died of heat stress in Myanmar's second largest city of Mandalay up to the weekend, the local 7-Day News quoted Mandalay municipal authorities as reporting Wednesday.

Mandalay's weather temperature was recorded at as high as 45 degree Celsius.

Among the dead, most were liquor drinkers, the report said, adding that the Mandalay local authorities have banned selling of liquor in the city.

The red-hot temperature has brought many patients of all ages to the Mandalay General Hospital and private clinics.

According to earlier official report, seven people died of heat stress in Taungdwingyi township, Myanmar's Magway division in the central part, over the past week.

Some drinking water ponds in suburban areas in Yangon also dried up due to excessively high weather temperature.

Over the period, thousands of fishes, bred in ponds in the country's southwestern Ayeyawaddy division, died of heat stress daily, local fish breeders said.

There were even some cases that all 100,000 fishes died in a single day in Twantay township, Yangon division.

Excessively hot weather temperature in Myanmar over the past two months broke the highest in the history.

From late April through to the mid-May, the day temperatures in central Myanmar were reaching a record high in over four decades, peaking at between 43 and 47 degree Celsius in such regions as Minbu, Magway, Mandalay, Monywa, Nyaung Oo, Chauk and Mingyan as well as in Yangon and Bago over the past week, which are 5 to 8 degree Celsius above April average temperature
