The prosecutor who inherited a high-profile case against Argentinian president Cristina Fernandez is reaffirming the accusations.
Gerardo Pollicita formally reopened the investigation into whether the president helped Iranian officials cover up their role in the 1994 bombing of a Jewish community centre.
Mr Pollicita was assigned the case his predecessor Alberto Nisman was building before he was found dead on January 18.
In a 289-page report to a judge, Mr Nisman accused Ms Fernandez, foreign minister Hector Timerman and others in her administration of brokering the cover-up in exchange for oil from Iran.
Ms Fernandez has strongly denied the accusations, and Tehran has repeatedly denied involvement in the bombing, which killed 85 people.
