UNHCR stands for the Office of the United Nations High Commissioner for Refugees. Commonly referred to as the the United Nations refugee agency, the UNHCR has a mandate to lead and co-ordinate international refugee protection actions and support refugees in their voluntary repatriation, local integration or resettlement to a third country. The UNHCR also provides humanitarian assistance to 'persons of concern' such as Internally Displaced Persons (IDPs) and others in their countries of origin.
