Pakistan heat wave death toll rises
The death toll in Pakistan's southern Sindh province, which has been struck by a heat wave, has reached 622, a senior health official has said.
Senior provincial health official Saeed Mangnejo said today that he expects the number of fatalities to climb further.
Mr Mangnejo says the death toll is for the past three days, though most of the deaths were reported in the province's largest city, Karachi.
Temperatures reaching 45C (113F) struck Karachi over the weekend.
Hours-long power outages also hit the city, leaving fans and air conditioners inoperable.
