The medial charity, MSF, has warned of a catastrophic humanitarian situation in a refugee camp in the Sudanese state of North Darfur.
MSF said all its emergency thresholds for malnutrition had been reached and called for an immediate increase in international aid.
It said at least one child was dying every two hours at the Zamzam camp, near the city of Fasher.
A war between Sudan's regular army and the paramilitary Rapid Support Force has displaced about eight million people since April last year.
Nearly five million people across Sudan now face emergency levels of hunger, the World Food Programme estimates. That's twice the number since the start of the conflict, it says.
The humanitarian body says it has only been able to deliver vital aid to 10% of those in need in areas embroiled in the conflict.
