A record seven million people - more than half of the country's population - in South Sudan are facing severe hunger, according to a report by its government and three United Nations agencies.

A lack of rain, ongoing economic crisis and years of civil war are being blamed for the worsening situation.

The report stopped short of declaring a famine, but says nearly two million people go without food for long periods and suffer acute malnutrition, leading to many deaths.

Over the past two years, the number of people needing food aid has increased by two million.

If the lack of rain and poor harvests continues, 21,000 people could suffer from famine.

What should be done to stop this disaster?
