By Brian Winter and Nicolás Misculin BUENOS AIRES (Reuters) – President Cristina Fernandez has portrayed Argentina’s spy agency as sinister, accountable to no one, and possibly responsible for the mysterious death of a prominent prosecutor in his Buenos Aires apartment. As a result, Fernandez declared this week, the Intelligence Secretariat needs to be totally shut down – and a new agency built from scratch. They say Fernandez has been in open conflict with her own spy agency for two years, following a deal in which she enlisted Iran’s help to investigate the 1994 bombing of a Jewish community center in Buenos Aires that killed 85 people.
