Argentinian Jewish leaders were in uproar this week after the lawyer investigating a cover-up over the bombing of the Amia Jewish centre was found dead hours before he was due to give evidence against the country's president.
Alberto Nisman was found on Sunday locked in his apartment in Buenos Aires, with a bullet through his temple and a handgun beside him. A preliminary autopsy suggested that he had committed suicide, although there is intense speculation in Argentina that he was the victim of an assassination.
Mr Nisman alleged last week that President Cristina Fernandez, her Foreign Minister Hector Timmerman and other officials had been involved in a "criminal conspiracy".
In a detailed document, he claimed they had "tried to erase Iran" from the 1994 Amia attack in Buenos Aires, which left 85 dead and was widely believed to have been perpetrated by Iranian agents.
