Lead found in '61 death of UN chief

New information in plane crash that killed Hammarskjold points to an aerial attack

A United Nations inquiry into a 1961 plane crash that killed then secretary-general Dag Hammarskjold found that new information pointing to an aerial attack or threat bringing down the aircraft warrants further investigation.

Hammarskjold - a Swede elected as the world body's second chief in 1953 - was killed along with 15 others while on his way to broker a truce in Katanga in what is now Democratic Republic of Congo. The plane crashed in Northern Rhodesia, now Zambia.
