A shocking humanitarian crisis has unfolded in Yemen since Saudi Arabia started its military campaign there in 2015. A country of 28 million people has 17 million people who are food insecure, 16 million people lack access to safe water and sanitation, and 16.4 million people lack access to adequate healthcare.

Two Chicago physicians with emergency experience recently came back from a humanitarian trip to Yemen. Dr. Zaher Sahloul and Dr. John Kahler offer their assessment of the health care needs of people in the port city of Aden. Sahloul is the co-founder of Med Global, a locally-based international humanitarian organization.
