Pakistan heatwave: Death toll crosses 800 people in Sindh
The death toll from a heatwave in Pakistan's southern Sindh province has passed 800, hospital officials say, as mortuaries reached capacity.
Matters have been made worse by power cuts, angering residents
At least 780 people had died in Karachi, BBC Urdu reported. Another 30 deaths were reported elsewhere in the province, state owned PTV said.
The Edhi Welfare Organisation told AFP that their mortuaries had received hundreds of corpses and were now full.
Officials have been criticised for not doing enough to tackle the crisis.
On Tuesday as temperatures reached 45C (113F), Pakistan's PM Nawaz Sharif called for emergency measures and the army was deploying to help set up heat stroke centres.
There is anger among local residents at the authorities because power cuts have restricted the use of air-conditioning units and fans, correspondents say.
Matters have been made worse by the widespread abstention from water during daylight hours during the fasting month of Ramadan.
On Tuesday, the National Disaster Management Authority (NDMA) said it had received orders from Mr Sharif to take immediate action to tackle the crisis.
Many of the victims are elderly people from low-income families.
Thousands more people are being treated, and some of them are in serious condition.
Hot weather is not unusual during summer months in Pakistan, but prolonged power cuts seem to have made matters worse, the BBC's Shahzeb Jillani reports.
Sporadic angry protests have taken place in parts of Karachi, with some people blaming the government and Karachi's main power utility, K-Electric, for failing to avoid deaths, our correspondent adds.
The prime minister had announced that there would be no electricity cuts but outages have increased since the start of Ramadan, he reports.
