Tensions are high between Argentina's Jewish community and the government since prosecutor Alberto Nisman was found dead on January 18.
Last week, Mr Nisman, who had been investigating the 1994 bombing of the Amia Jewish centre, was laid to rest in the same section of La Tablada - the main Jewish cemetery in Buenos Aires - where many of the 85 killed in the Amia attack are also buried.
For the first time since 2005, Argentina's two main Jewish bodies, Daia and Amia, refused to join last week's Shoah ceremonies at the Foreign Ministry.
They were protesting over Mr Nisman's death and because January 27 marked the second anniversary of the signing of the Argentinian-Iranian Memorandum of Understanding, under which the two countries pledged to jointly probe the Amia attack.
Some factions have called for the man who signed the accord, Héctor Timerman - Argentina's Foreign Minister, who is Jewish - to withdraw his membership of Amia. "Why was an agreement signed with a country that denies the Holocaust?" asked Daia's treasurer, Mario Comisarenco.
Mr Nisman died hours before he was due to present evidence to support his claim that President Cristina Fernández de Kirchner had covered up Iran's involvement in the attack - an accusation she rejects.
This week, two judges refused to pursue the accusations against Ms Kirchner. The allegations will now move to a federal chamber.
