The United Nations has issued a grave warning about the humanitarian situation in Somalia — over 10 months after the U.S.-backed Ethiopian invasion.

Eric Larouche, U.N. humanitarian coordinator: “The humanitarian crisis is very bad. It’s the worst humanitarian crisis that we have had in the last 15 years. It reminds us of the beginning of the '90s, so it's not very good news. We had a few months ago only — I mean, we had already 400,000 people that were displaced because of the conflict and because of the natural disaster. Today, we have 850,000 people, so we have more than doubled the number of people that are displaced in Somalia.”

Nearly 90,000 people have fled the capital Mogadishu since violence increased last week. Ethiopian troops continue to pour into the country to combat Islamist militants.
