Argentina:Nisman knew "the most" on AMIA attack (AMIA president) Argentine prosecutor Alberto Nisman was found dead in his Buenos Aires home Sunday, just hours before he was to go before a congressional hearing to accuse President Cristina Kirchner of shielding Iranian officials implicated in a bomb attack on the AMIA Jewish community center in 1994 that left 85 dead. "A great deal of what was known about the AMIA case died with Prosecutor Nisman," the executive director of AMIA Ariel Cohen told AFP on Friday. IMAGES AND SOUNDBITES
