Nisman, who had been under the protection of a 10-member security detail, was set to testify Monday to lawmakers on a report alleging that President Cristina Fernández de Kirchner and Foreign Minister Héctor Timerman had covered up Iran’s involvement in the attack. The bombing left 85 people dead and some 300 wounded.
Argentine prosecutors have long accused Iran of involvement in the bombing and requested the arrest of several Iranian citizens in connection with it. Iran has denied the charges.
