She added that the country's military have not acknowledged human rights abuses which took place during the dictatorship in Brazil.
Brazil's National Truth Commission investigates violations of human rights committed during the country's military dictatorship between 1964 and 1985.
The current president of Brazil was arrested, tried and sent to prison in 1970 because of her involvement with guerrilla groups opposing a military dictatorship in Brazil that came to power in the 1964 coup.
