Since conflict broke out in December 2013, more than 10,000 people have lost their lives. 1.5 million people forced from their homes are seeking safety in South Sudan, while the number of South Sudanese refugees in neighbouring countries has risen to over 500,000.
In total, 4.9 million people need urgent humanitarian support now - including 200,000 children suffering severe acute malnutrition - and 7 million risk not having enough to eat in the months ahead unless international aid is dramatically and urgently increased.
Many have had to leave behind their possessions, crops and livestock or sell their assets to escape and have no means to buy food, water and other essentials. Most people were not able to plant crops, so there will be no harvest in the coming months and no food stored to see them through next year.
Camps are becoming overcrowded and poor sanitation is increasing the risk of disease, with reported cases of cholera in the capital Juba increasing.
