The convoy began moving across the border last Friday and carried enough supplies -- food, blankets, mattresses, hygiene kits, medicines and medical supplies for 268,000 people. It was organized by an alphabet soup of U.N. agencies: the Office for the Coordination of Humanitarian Affairs (OCHA), the World Food Program (WFP), the Office of the UN High Commissioner for Refugees (UNHCR), the United Nations Childrens Fund (UNICEF), the World Health Organization (WHO), and the International Organization for Migration (IOM).
