Levels of hunger in the Democratic Republic of Congo have doubled since last year according to a new report by the UN and the Congolese government.

It says close to half of all children under the age of five are suffering from malnutrition and more than 13 million people, nearly a fifth of the Congolese population, do not have enough food.

In addition to a poor harvest, the report says the crisis is especially acute in North Kivu and Ituri provinces in eastern DR Congo where violence has displaced thousands.

It warns that farmers there are scared of working in their fields and young people are joining armed groups and going into prostitution to find money for food.
