REUTERS - The United Nations appealed on Wednesday for $459 million in aid for flood-hit Pakistan, warning of a second wave of death among sick, hungry survivors unless help arrived quickly.
 Roiling floods triggered by unusually heavy monsoon rain have scoured Pakistan's Indus river basin, killing more than 1,600 people, forcing 2 million from their homes and disrupting the lives of about 14 million people, or 8 percent of the population.
