Prime Minister Yousuf Raza Gilani said Saturday that the catastrophic floods had affected 20 million people in his country, up from an earlier UN estimate of 14 million victims. "Torrential rains and devastating floods have made 20 million people homeless, destroyed standing crops and food shops and storages of worth of billions of dollars, washed away bridges, roads, communication and energy networks," dpa quoted Gilani as saying in a 63rd-Independence Day televised address. Gilani said that the floods had killed 1,384 people, injured 1,630 and destroyed 730,000 houses. In the north-western district of Khyber-Pakhtunkhwa, 24 out of 25 districts were affected. The swollen Indus River also caused widespread devastation in the central province of Punjab and southern province of Sindh.
