War and natural disasters
It is five years since a new future for Afghanistan was mapped out at an international conference in Bonn.
But Afghanistan is still the poorest country in Asia. Growing insecurity and lawlessness have put vast areas of the country beyond the reach of humanitarian workers.
The majority of its people still lack safe drinking water and health care. Fewer than 10% of Afghanistan's 30 million people have electricity. Landmines still litter much of the country.
