Former anti-apartheid activist Alpheus Manghezi recalls the day in August 1982 when his colleague Ruth First was killed by a parcel bomb delivered to her office. Both Manghezi and First were living in exile in Mozambique. Manghezi describes how he visited the scene together with the Mozambican president, Samora Machel. The assassins were later identified as agents of the South African state.
