Africa/Global: UN says 50 million displaced failed by governments

More than 50 million people in the world have fled their homes because of conflict and disaster, but do not receive the help given to international refugess because they have not crossed into a foreign country. The United Nations said on Tuesday many internally displaced people (IDP) live in abject conditions, ignored by their governments and the international community. "This is a massive global humanitarian problem -- something on the scale of the HIV/AIDS crisis but getting much less attention," said U.N. official Dennis McNamara, new head of a unit set up to tackle the issue.
