Truth Commission expands human-rights investigation
SAO PAULO — The Truth Commission investigating human-rights abuses committed by Brazil’s former dictatorship also will look into the role Catholic and evangelical churches played under the military regime from 1964 to 1985.
Commission member Paulo Sergio Pinheiro says the activities of clergy who opposed the dictatorship as well as the actions of religious groups that backed the regime will be investigated.
President Dilma Rousseff, a former leftist guerrilla who was imprisoned for more than three years and tortured during the dictatorship, last year signed the law establishing the commission. It was given two years to conclude its investigation.
