In 1974 the World Council of Churches affirmed that large numbers of people had been murdered since 1968 in an ongoing reign of terror. A quarter of the entire population had fled abroad, they said, while 'the prisons are overflowing and to all intents and purposes form one vast concentration camp'. Out of a population of 300,000, an estimated 80,000 were killed. Apart from allegedly committing genocide against the ethnic minority Bubi people, Macias Nguema ordered the deaths of thousands of suspected opponents, closed down churches and presided over the economy's collapse as skilled citizens and foreigners fled the country.
