Pakistan's worst flooding

Hundreds of people have died in northwestern Pakistan after floods triggered by monsoon rains swept through the region. More than a million people have been affected and thousands forced to flee their homes as bloated rivers washed away villages and triggered devastating landslides. Rescue operations are under way to save the stranded, but submerged roads and destroyed infrastructure are proving to be major obstacles.
