A federal judge in Argentina indicted and asked for the arrest of former President Cristina Fernandez for trying to cover up Iran's possible role in the bombing of a Jewish community center in 1994 that killed 85 people, state news agency Telam said on Thursday.
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.
Judge Carlos Bonadio also ordered the arrest of former foreign minister Hector Timerman and several other former officials in the Kirchner governments. Investigators have linked former Iranian officials to the attack, but Iran has denied any connection with the attack and declined to turn over suspects. In January 2015, the prosecutor who initially made the accusation, Alberto Nisman, was found shot dead in the bathroom of his Buenos Aires apartment.
Kirchner, 64, who had two 4-year terms in office, is due to take her seat in the Senate next week after her election victory in October crowned a political comeback and granted her immunity from imprisonment in several corruption cases.
The Jewish center bombing case is the most serious before Kirchner, who is facing trial in several other cases involving corruption and money laundering stemming from her years as president. Last week, the court rejected an appeal by Mrs Kirchner to dismiss the laundering charges.
Argentine newspaper Clarin reported, however, that Congress was unlikely to secure the two-thirds majority vote to do so - meaning her detention was not expected. The center-right Cambiemos alliance of President Mauricio Macri has 25 seats in the upper house. She was president from 2007 to 2015.
