Argentina's disappeared finally being traced

An investigation into the fate of many people who disappeared under the Argentine junta suggests many of them were thrown from aircraft into the vast Parana Delta.

Official accounts suggest almost 20,000 people were "disappeared" in the regime's "Dirty War" between 1976 and 1983, but human rights groups say the figure is closer to 30,000.

Vladimir Hernandez reports from the Parana Delta.
