Secretary-General Ban Ki-moon says an independent panel of experts that examined new information about the mysterious 1961 plane crash that killed Secretary-General Dag Hammarskjold on a peace mission to newly independent Congo has delivered its report.

U.N. spokesman Stephane Dujarric said Friday that Ban will study the panel's findings, conclusions and recommendations and release it as soon as possible with his own assessment "and options on the way forward."

Hammarskjold's plane crashed over the African bush in Northern Rhodesia, today's Zambia. One issue for the panel is whether the plane was shot down.

Dujarric said Ban is pleased that the panel visited Zambia to meet with new witnesses, and that it gathered new information from member states and other sources including national and private archives in Belgium, Britain and Sweden.
