U.N. Secretary-General Ban Ki-Moon will travel to Haiti on Sunday to show his solidarity with the people of the earthquake-stricken country, the United Nations said on Friday. Moon will assess the humanitarian aid effort and the scale of the disaster for himself, the world body said in a statement quoted by Reuters. Moon met with Haitian staff at the United Nations on Friday to offer his condolences for the many lives lost in the quake. The U.N. peacekeeping mission in Haiti, which lost at least 36 of its personnel in the disaster, is trying to provide some basic co-ordination of the international relief effort from an office near the airport at Port-au-Prince.
