An Argentine federal judge has ordered that the former president Cristina Fernández de Kirchner be jailed pending prosecution in connection with charges that she helped to hide Iran's alleged involvement in a 1994 terrorist attack in Buenos Aires in which 85 people died.
Meanwhile, the judge issued arrest warrants for the ex-president's Foreign Affairs Minister Hector Timerman and legal and technical secretary Carlos Zannini.
Cover-up or "act of foreign policy"? .
According to Bonadio, the memorandum of understanding signed with Iran was created to ensure "impunity" for the Iranians suspected of the crime and "normalize relations between the two states".
The original case was brought by prosecutor Alberto Nisman who was found dead with a bullet in his head the day before he was scheduled to present his evidence before Congress. Nisman's case was rejected by another judge before being revived by Claudio Bonadio.
Years after the attack on the Asociación Mutual Israelita Argentina (AMIA), Kirchner was accused of having struck a deal with Iranian officials to grant those responsible for the bombing immunity in exchange for oil, the Telegraph reports.
Nisman, 51, was found dead in his apartment here on January 18, 2015, of a gunshot wound to the head.
Kirchner told the press conference that the signing of the memorandum in 2012 "was an act of foreign policy that can not be prosecuted". Iran denies any involvement.
"It is an invented case about facts that did not exist", said the former president, who governed from 2007 to 2015.
"The case was absolutely paralyzed because Iran does not extradite its compatriots".
She has previously called the case an "absurdity", and pointed out that both she and her husband Nestor, the former president, were instrumental in pushing for an investigation into the attack. "What we did was to act within the framework of global law", she said.
The removal of Fernandez's immunity from arrest needs a two-thirds majority vote in the Senate.
The attack - which followed a 1992 bombing of the Israeli embassy in Buenos Aires that killed 29 people - devastated Argentina's Jewish population, the largest in Latin America at about 300,000 people.
Kirchner's leftist alliance in the Senate has a total of 32 seats in the 72-seat Senate, but only around a dozen senators are in the Kirchner camp.
She argued that since Iran and Argentina have no extradition agreement, and Argentina does not carry out trials in absentia, there was no other way to proceed with the investigation.
