With over twenty million people reliant on aid, Yemen is the world's single largest humanitarian crisis. The war-torn nation is currently in the grip of a deadly cholera outbreak. Experts of the International Committee of the Red Cross (ICRC) expect the current number of suspected cholera cases to at least double by the end of 2017 to over 600-thousand. ICRC president Peter Maurer is currently on a five day visit to Yemen to discuss the humanitarian situation with country's officials. More from the ICRC's Ralph El Hage.
