Argentine Plaza de Mayo activists lobby Pope Francis

Argentine activists searching for missing victims of the Dirty War have met Pope Francis, who was a priest in Argentina during military rule.

The Grandmothers of the Plazo de Mayo group asked the Pope to open Vatican archives from the 1976-1983 period.

The activists are trying to trace hundreds of babies that were snatched from political prisoners.

The group's leader Estela de Carlotto said the Church must know where some of the children were taken.
