Secretary-General Ban Ki-moon is calling for a review of potential new information, including from South Africa, on the mysterious 1961 plane crash that killed U.N. Secretary-General Dag Hammarskjold.

Ban recommended in a note to the U.N. General Assembly circulated Wednesday that either he or the 193-member world body appoint "an eminent person or persons" to conduct the review and "determine the scope that any further inquiry or investigation should take."

The General Assembly unanimously adopted a resolution last November urging all countries — especially the United States, Britain and South Africa — to release all information on the crash in what is now Zambia while Hammarskjold was on a peace mission to newly independent Congo.

Ban reiterated that appeal, stressing U.N. members must "pursue the full truth" about his death.
