Nearly five million people in Somalia are suffering from a shortage of food due to poor rainfall, floods and displacement, the United Nations says.
More than 300,000 children under the age of five are severely malnourished and require urgent assistance.
Most of those in need of help have been internally displaced following decades of conflict.
Malnutrition levels in Somalia have increased over the last six months with nearly half the population affected.
The number of people without enough food has increased by 300,000 since February.
Somalia drought leaves children ‘facing death’
Peter de Clercq, the UN humanitarian coordinator for Somalia, said those providing aid were ready to “scale up” their response to help families struggling to find food.
But he noted that funding for the Somalia Humanitarian Response Plan has reached just 32% of its target.
