as many as 13 million people throughout the South Asian nation have been affected by the rising waters.
About 1,500 people have died, most of them in the northwest, the hardest-hit region.
The intense flooding that began about two weeks ago has washed away roads, bridges and many communications lines, hampering rescue efforts. Incessant monsoon rains have grounded many helicopters trying to rescue people and ferry aid, including six choppers manned by U.S. troops on loan from Afghanistan.
