Last month, an Argentine prosecutor who was due to testify about an alleged cover-up in the investigation into the deadly 1994 bombing of a Jewish center in Buenos Aires was found dead.
Alberto Nisman had accused President Cristina Fernandez de Kirchner's government of covering up Iran's alleged role in the bombing that killed 85 people to push through a grains-for-oil deal with Tehran. After Nisman's death, the investigation was continued by prosecutor Gerardo Pollicita.
Thursday, a judge dismissed the accusations, saying the documents filed by prosecutors had failed to meet the minimum standards for a formal investigation.
Kirchner had previously dismissed the allegation of a secret deal with Tehran as "absurd."
Nisman was found dead in his apartment last month with a gunshot wound to the head. A prosecutor said there appeared to be no outside involvement in the death, but investigators were treating it as suspicious.
Kirchner waded in, saying Nisman's death "was not a suicide," sparking conspiracy theories in the country over his death and his investigation. She then dissolved the country's intelligence agency, suggesting it was tied to Nisman's death and saying it "has not served the national interests."
NPR's Lourdes Garcia-Navarro, who has been reporting on this story, says there's a reason Argentina is riveted by this case and its cast of characters, both major and minor:
"Part of this fascination has to do with Argentina's murky, bloody history. The country suffered a brutal dictatorship under which people disappeared and babies were stolen to be brought up by their parents' torturers. Conspiracy theories in Argentina often turn out to be true."
Thursday, the country's Congress also approved a law overhauling the intelligence agency, replacing it with a new intelligence service.
