<P> The United Nations maintains and supports a number of specialized organizations and agencies . These differ from the programmes and funds in that they are headed by an executive board of member states, separate from the General Assembly . Sometimes they do not report to the General Assembly or Security Council but only to their own member states . Some of these bodies also predate the United Nations as is the case for the ITU formed in 1865 to administer an international treaty and the ILO created as part of the League of Nations . </P> <Table> Specialized organisations and agencies of the United Nations <Tr> <Th> No . </Th> <Th> Acronyms </Th> <Th> Agency </Th> <Th> Headquarters </Th> <Th> Head </Th> <Th> Established </Th> <Th> Comment </Th> </Tr> <Tr> <Td> </Td> <Td> FAO </Td> <Td> Food and Agriculture Organization </Td> <Td> Rome, Italy </Td> <Td> José Graziano da Silva </Td> <Td> 1946 </Td> <Td> </Td> </Tr> <Tr> <Td> </Td> <Td> IAEA </Td> <Td> International Atomic Energy Agency </Td> <Td> Vienna, Austria </Td> <Td> Yukiya Amano </Td> <Td> 1957 </Td> <Td> Associated agency </Td> </Tr> <Tr> <Td> </Td> <Td> ICAO </Td> <Td> International Civil Aviation Organization </Td> <Td> Montreal, Quebec, Canada </Td> <Td> Fang Liu </Td> <Td> 1947 </Td> <Td> </Td> </Tr> <Tr> <Td> </Td> <Td> IFAD </Td> <Td> International Fund for Agricultural Development </Td> <Td> Rome, Italy </Td> <Td> Gilbert F.
