The group first came to national attention on 21 November 1973 in its attempt to murder Argentine Senator Hipólito Solari Yrigoyen by a car bomb. The AAA went on to kill 1,122 people, according to an appendix to the 1983 CONADEP report, including suspected Montoneros and ERP leftist terrorists and their sympathizers, but the group expanded its targets to other political opponents, including judges, police chiefs, and social activists. In total, it is suspected of having killed more than 1500 people.
