A woman holds a sign on a police fence that reads “Kretina assassin”, in reference to President Cristina Fernandez de Kirchner, during a protest over the death of prosecutor Alberto Nisman, in front of the Olivos presidential residence in Buenos Aires January 19, 2015. Nisman, who accused Fernandez of orchestrating a cover-up in the investigation of Iran over the 1994 bombing of a Jewish community center, was found dead in his apartment, authorities said on Monday. Nisman, who had been delving into the blast at the AMIA Jewish community center in Buenos Aires that killed 85 people, said Wednesday that Fernandez opened secretive discussions with Iran and at least one of the men suspected of planting the bomb.
