Displaced, repatriated & crossing borders: Afghan people make gruelling journeys to survive

The sprawling camp of people returning to Afghanistan through the Torkham border crossing is the latest facet of Afghans' long, painful search for a stable home. More than 40 years of war, violence and poverty in Afghanistan have created one of the world's most uprooted populations. Some 6 million Afghans are refugees outside the country. Another 3.5 million people are displaced within the country of 40 million, driven from their homes by war, earthquakes, drought or resources that are being depleted.
