The head of the United Nations Children's Fund (UNICEF) said Monday that 3 million Haitian children caught up in rampant gang violence are in need of humanitarian assistance, including thousands who are at risk of dying from severe malnutrition. Meanwhile, a sharp increase in the number of wounded has put enormous pressure on the few functioning hospitals in Haiti's capital, Port-au-Prince, as they run dangerously low on medical supplies, the International Committee of the Red Cross (ICRC) warned.
