Fourteen foreigners went on trial in the tiny oil-rich state of Equatorial Guinea on Monday, charged with plotting a mercenary invasion to overthrow President Teodoro Obiang Nguema, a government official in the capital Malabo said. The eight South Africans and six Armenians were arrested in Malabo on 6 March. They were charged with conniving with 70 South African mercenaries who were arrested 24 hours later in Zimbabwe as they were allegedly on their way to Equatorial Guinea to mount an invasion.
