Pakistan heatwave deaths near 700

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

Pakistan's PM Nawaz Sharif has called for emergency measures as the death toll from a heatwave in southern Sindh province reached nearly 700.

The army is now being deployed to help set up heat stroke centres, with temperatures reaching 45C (113F).

Officials have been criticised for not doing enough to tackle the crisis.

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.
