Investigators call for new Hammarskjöld probe
International investigators have called on the United Nations to reopen an investigation into a plane crash in the 1960's which killed Swedish UN Secretary General Dag Hammarskjöld.
The investigators claim information stored by the US National Security Agency could provide clues as to why Hammarskjöld's plane crashed in central Africa in 1961.
The investigators believe the agency may have stored cockpit recordings that could put some light as to whether his plane crashed, or was shot down. So far the agency has refused investigators requests to look at the documents, saying they are classified top secret.
One of the investigators, Hans Corell, told news agency TT the NSA information could be "decisive".
