Romania's government has declassified secret documents relating to prisons where hundreds of thousands of opponents of the former communist regime were incarcerated.

The government said Wednesday it was declassifying documents from 1957 to 1962 which were "necessary for solving ongoing trials."

Alexandru Visinescu is on trial accused of crimes against humanity for the deaths of 12 prisoners at Ramnicu Sarat, where he was commander from 1956 to 1963.

Ion Ficior faces the same charges for the deaths of 103 people at Periprava labor camp, which he ran from 1958 to 1963. Both have denied wrongdoing.

About 500,000 Romanians were held as political prisoners.
