The UN says the war in Sudan is having a devastating impact on the whole country and could tip the entire region into a humanitarian catastrophe.
Fighting between the army and a paramilitary force began in April and is spreading.
The UN says hundreds of thousands of children are severely malnourished and are at imminent risk of death if left untreated.
The UN’s Humanitarian Co-ordinator says hunger, disease and displacement are threatening to totally destroy Sudan.
There have been many grim reports about the impact of the war but Martin Griffiths is suggesting that if the fighting between the army and the Rapid Support Forces continues, the whole region will face dire consequences.
This week the charity Save The Children said because of the violence it had been forced to close down dozens of its nutrition facilities.
It said more than 30,000 children were missing out on treatment and as a result close to 500 had died.
