The United Nations is warning the famine in Somalia has not peaked.

More than 12 million people are still at risk as the worst drought in 60 years plagues the horn of Africa.

Now, the World Health Organization says the entire region is facing a cholera epidemic due to dirty water and poor sanitation.

The United Nations says without a massive global response hundreds of thousands of people face imminent starvation and death.

Tony Hall, executive director of the Alliance to End Hunger, recently visited the refugee camps in Dadaab, Kenya.

During a telephone interview with CBN News from Nairobi, he talked about about the greatest needs in the camps.

"I think there are great needs for food, water, sanitation, for non food items, things that people need. These people have escaped Somalia with just whatever they can carry," he noted.

"I thank the U.N., the U.S. government, the private organizations, the Americans that have been donating money," Hall added. "I think they can feel really good because their money is being, I think, served well."

"It's the moral and right thing to do. And I think our country, I think every country, is judged by how they take care of the least of these," he said.
