The case against President

Argentine prosecutors formally accused President Cristina Fernandez de KirchnerFriday of shielding Iranian officials from prosecution over a 1994 Jewish center bombing, renewing the firestorm around the embattled leader.

The accusation advances the case againstKirchner that was being pursued by late prosecutor Alberto Nisman before he died mysteriously on the eve of congressional hearings on his allegations.

Nisman, 51, was found in his Buenos Aires apartment with a gunshot to the head after alleging that Kirchner had protected high-ranking Iranian officials from prosecution over the bombing in exchange for oil.
