Argentine grandmothers still searching for 'stolen' babies

The fate of stolen babies is one of the most painful legacies of Argentina's "Dirty War". During this period, up to 30,000 people were killed - or were made to "disappear" - by the armed forces, according to rights groups.

Children born to mothers held in detention centres were given to police or army families. Many were brought up not knowing they were adopted and only found out as adults. Many more still do not know that they were seized from their parents.

BBC Newsnight's Sue Lloyd Roberts has been to Buenos Aires to meet the Grandmothers of the Plaza de Mayo, an organisation which aims to find the children taken during the 1976-1983 dictatorship.
