Secretariat of Intelligence was the premier intelligence agency of the Argentine Republic and head of its National Intelligence System.

Natalio Alberto Nisman was an Argentine lawyer who worked as a federal prosecutor, noted for being the chief investigator of the 1994 car bombing of a Jewish center in Buenos Aires, which killed 85 people, the worst terrorist attack in Argentina's history. On 18 January 2015, Nisman was found dead at his home in Buenos Aires, one day before he was scheduled to report on his findings before a Congress inquiry with supposedly incriminating evidence against high-ranking officials of the then-current Argentinian government including former president Cristina Fernández de Kirchner, regarding the Memorandum of understanding between Argentina and Iran.
