Folha reports that documents uncovered by the Brazilian truth commission reveal the existence of a previously unknown archive of the armed forces about the dictatorship period. An operation known as "Netuno" (Neptune) was dedicted to preserving documents on microfilm between 1972 and 1974. The archive, whose whereabouts are still unknown, is thought to run to at least 1.2 million pages. The military denies all knowledge of it.
