Mothers of Plaza de Mayo: 35 years of struggle
30 April 2012
Today, April 30, it is the 35th anniversary of the founding of the organization Mothers of Plaza de Mayo, which has begun the search for the people who were reported missing during Argentina’s military dictatorship (1976-1983). In their struggle, these mothers have been accompanied by relatives of missing persons and other organizations such as the Grandmothers of Plaza de Mayo among others.
From daily The Morning Star in Britain today:
ARGENTINA: Estela Carlotto, the 83-year-old leader of the Grandmothers of the Plaza de Mayo group, which has fought to find babies stolen during the 1976-1983 “dirty war,” finally found her long-lost grandson yesterday.
Her daughter, left-wing activist Laura Carlotto, was three months pregnant when she was taken to a prison camp in 1977.
She gave birth while in captivity but was killed two months after her son was born.
