Pakistan’s southern Sindh province is on red alert as flood waters sweep down from the north.
The worst monsoon rains in eight decades battered the northwest of the country over a week ago, leaving several hundred thousand homeless.
The rainfall has affected an estimated 12 million people and the government says more than 1,600 have died.
With many Pakistanis fighting to survive, questions have been raised about President Asif Ali Zardari’s decision to press ahead with an official visit to Britain as his country struggles with this catastrophe.
Authorities yesterday evacuated half a million people from the Sindh province as the region braced itself for the worst.
The floods have destroyed roads and bridges, hampering aid agencies’ efforts in distributing food and medicine.
Flash floods have also taken their toll in neighbouring India along the border with the Himalayas.
At least 132 people are known to have died in the region of Ladakh in Indian-controlled Kashmir.
But officials concede that figure is likely to rise as many more remain unaccounted for.
India’s military is assisting with the rescue operation to find survivors.
