Mozambican President Daniel Chapo has called for renewed efforts to determine how former president Samora Moisés Machel died. Machel, Mozambique's first president, died in a plane crash at Mbuzini in South Africa 40 years ago. Chapo's appeal focuses on establishing the circumstances of the crash and any facts that remain unresolved. No aircraft type or cause of the accident is identified in the available report. Earlier investigation findings are not summarized, and it is unclear whether new evidence prompted the president's request. The issue brings present-day political scrutiny in Mozambique to an event that happened outside the country nearly four decades ago.
