It is 35 years since the Mothers of the Plaza de Mayo group first began marching for justice around Buenos Aires' central square.

Since 1977, the women have taken to the streets every Thursday to highlight the tens of thousands of children who disappeared during what is known as Argentina's "Dirty War."

Human rights groups estimate that more 30,000 people were kidnapped, tortured or murdered during the brutal military dictatorship.
