President Cristina Fernandez called on Congress to dissolve Argentina’s intelligence services in the wake of the mysterious death of a prosecutor, strongly denying his accusation that she had sought to shield former Iranian officials suspected in the 1994 bombing of a Jewish center.

In a nationally televised address late Monday, her first since the death of prosecutor Alberto Nisman hours before he was to give potentially explosive testimony on the alleged cover-up, Fernandez said her proposal to create a new spy agency would be presented to lawmakers by the end of the week.
