A teenage Pashtun boy collects dirt, left by floods outside a residence, to sell in a nearby market in Charsadda, northwest Pakistan September 25, 2010. The floods, Pakistan's worst natural disaster in terms of damage and the number of people affected, were triggered by monsoon rains in late July, displacing 10 million people.
