Esther Acuma has tied her dead 10 month old son to her back. He died the previous night of severe malnutrition. She is carrying his body back to her village by cycle taxi, a journey that will take 4 hours. For 18 years the Lord's Resistance Army (LRA) rebels have terrorised the Northern provinces of Uganda abducting 20,000 children and forcing 1.6 million people to flee their homes.

The UN's under-secretary general for humanitarian affairs has called Northern Uganda the "largest neglected humanitarian emergency in the world".
