The death toll from a heatwave in Pakistan's southern Sindh province has passed 800, hospital officials say, as mortuaries reached capacity.

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.

Thousands of people are being treated in the Sindh province, and some of them are in serious condition

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.
