World Notes South Africa

After two Soviet-made limpet bombs exploded last March in the women's toilet of Johannesburg's police headquarters, police arrested Marion Sparg, 28, a former reporter for the Johannesburg Sunday Times. She confessed to the bombing, which miraculously killed no one, and to planting explosive devices in two other police stations.

Sparg, who is white, then identified herself as a guerrilla of the African National Congress, the outlawed antiapartheid political organization. Last week, dressed defiantly in the A.N.C.'s colors of black, green and yellow, she pleaded guilty to charges of treason, arson and attempted arson and was sentenced to 25 years in prison.
