Secretary of State John Kerry is in Africa to promote peace in South Sudan.
Violence between ethnic groups has been raging in the country for nearly six months, despite the presence of U.N. peacekeepers.
"Currently the United Nations estimates that some 5.9 million people in South Sudan are in need of humanitarian assistance. Those numbers will probably only go up as the rainy season bites and people run out of food," Peter Smerdon, with World Food Programme, said.
Now foreign ministers from Ethiopia, Kenya, and Uganda are meeting with Kerry to figure out how to help end the crisis. With millions in need in the country, they say time is crucial.
"What is critical is that the hostilities have to be ceased and that both leaders come together so that the people of this country South Sudan not be betrayed," Adama Dieng, special advisor on Prevention of Genocide said.
The United States has threatened sanctions against South Sudan if the violence doesn't end soon.
