The United Nations is warning food, water and other basic supplies are running short in parts of Libya. Valerie Amos is the United Nations humanitarian chief.

Valerie Amos, United Nations Humanitarian Chief: “Widespread shortages are paralyzing the country in ways in which will impact gravely on the general population in the months ahead, particularly the poorest and the most vulnerable. We do not yet have an accurate figure of the total number of casualties since the start of the crisis. The longer the current situation continues, the graver the humanitarian situation will become. With this in mind, the United Nations has established a humanitarian presence in both Benghazi and Tripoli.”
