Pakistan survivors stalked by disease as waters ebb

A month after torrential monsoon rains triggered Pakistan's worst natural disaster on record, flood waters are starting to recede -- but there are countless survivors at risk of death from hunger and disease. The disaster has killed at least 1,643 people, forced more than six million from their homes, inflicted billions of dollars of damage to infrastructure and the vital agriculture sector and stirred anger against the U.S.-backed government which has struggled to cope. Despite generally lower water levels, officials said they were still battling to save the delta town of Thatta, 70 km (45 miles) east of Karachi, in the southern province of Sindh. Water has broken the banks of the Indus near Thatta and also topped a feeder canal running off the river.
