Argentina: Hunting Argentina's stolen children

The Argentinian government is trying to find hundreds of children stolen from their parents during the military dictatorship of the 1970s and early 1980s.

A controversial law obliges young adults suspected of being the missing children to provide DNA sample, even if they do not want to be found.

The adopted children of one of Argentina's most powerful women are at the centre of the debate.
