ARGENTINA-ISRAEL-IRAN-AMIA-NISMAN-DEMO

President Cristina Kirchner urged Argentines to be on guard Wednesday ahead of a mass protest over the mysterious death of Nisman who had accused her of a cover-up in his probe of a 1994 bombing. Nisman was found in his Buenos Aires apartment with a bullet through his head on January 18, the day before he was to go before a congressional hearing to air his finding that Kirchner and her foreign minister plotted to shield Iranian officials implicated in the bombing of the AMIA Jewish-Argentine charity.
