Brazil's Senate has approved the creation of a truth commission to investigate human rights abuses by the military regime that ruled Latin America's biggest country from 1964 to 1985.
The bill creating the commission was approved Wednesday night. It was approved by the lower house Chamber of Deputies in September.
Unlike Argentina, Chile and Uruguay, Brazil has never punished military officials accused of human rights abuses during military rule.
A recent study by the Brazilian government said 475 people were killed or "disappeared" by agents of the military regime.
