Prosecutor Alberto Nisman was found dead in 2015 after accusing Cristina Fernández de Kirchner of hiding alleged involvement of Iranians in 1994 attack

An Argentinian court on Thursday ordered a renewed investigation into a prosecutor’s accusation that former president Cristina Fernández de Kirchner covered up the alleged involvement of Iranians in a bombing that killed 85 people.

The attack on a Jewish community centre in Buenos Aires in 1994 wounded hundreds of others. The country’s top criminal tribunal accepted a request by a coalition of Argentinian Jewish associations to re-examine the charge against Fernández, her foreign minister Héctor Timerman and other officials in her government.

Prosecutor Alberto Nisman made the charge against Fernández on 14 January 2015. He was found dead with a gunshot to the head four days later. Authorities never determined if he was killed or took his own life.

Iran has denied any connection with the attack and declined to turn over the suspects in the case. Fernández was president from 2007 to 2015. She has denied wrongdoing in the case.

The former president blames the accusation on what she says is the bias of judges following the orders of her successor, President Mauricio Macri, who took office in December 2015.

Santiago Kaplun, the secretary general of the delegation of Jewish organisations, welcomed the court ruling, telling the Todo Noticias cable TV channel: “We are very hopeful.”

The ruling adds to the legal complications facing the former leader. On Tuesday, a federal judge approved charges of illicit association and fraudulent administration against Fernández, and two former aides: ex-planning minister Julio de Vido and former public works secretary Jose Lopez. They are accused of misusing public money by paying inflated prices for public works contracts. Fernandez also denies wrongdoing in that case.
