The world has as little as three months to save millions of people from famine in and Somalia, the International Committee of the Red Cross said on Wednesday.
The medical charity needs $300m to bring emergency assistance to a total of five million people in Yemen, Somalia and northeast Nigeria, as well as areas of South Sudan where famine has already been declared.
The funds will ensure that five million of the 20 million people at risk of famine and starvation receive immediate and essential aid, said Red Cross director of operations Dominik Stillhart.
"Food, water, shelter, and healthcare is required immediately," he said.
"We are on the ground and delivering aid in all four countries. We witness the massive suffering. Millions of people are denied the very basics to survive."
