(CNN) -- An Argentine government report released Tuesday alleges that two of the country's largest newspapers, Clarin and La Nacion, resorted to human rights violations against the owners of a paper company in what was an illegal appropriation of its shares. Founded in 1972, Papel Prensa is the main manufacturer of newsprint in Argentina and is owned by Clarin, La Nacion, and the government. The report alleges that the two newspaper conglomerates colluded with Argentina's dictatorship in 1976 to force the sale of the shares through torture and threats. Both newspapers have denied the claims, and say the shares of Papel Prensa were bought legally.
