The Truth and Reconciliation Commission in South Africa is today holding a closed-session inquiry into the plane crash which killed Mozambique's president, Samora Machel, in 1986.

The Commission announced the inquiry last month after it said new evidence had emerged implicating the South African army in the crash which happened just inside South African territory.

Samora Machel was one of the fiercest opponents of apartheid, and allowed the then outlawed African National Congress to launch guerrilla attacks from Mozambique against the South African government.

The government blamed the crash on bad weather and pilot error, but survivors questioned that conclusion.

Samora Machel's widow, Graca, is now President Nelson Mandela's close companion, and he's said to have promised her that he will find out how her husband died.
