Telesur reports that Alberto Nisman was found dead in his apartment hours before he was scheduled to appear before Argentina's Congress on Monday to give his report on the bombing.
According to the New York Times, the mysterious death followed the ousting of an intelligence official, Antonio Stusso, who is suspected of having fed Nisman misleading information about the case. Acording to US diplomatic cables revealed by Wikileaks, the prosecutor was also being advised by the US and Israeli intelligence services, according to Telesur.
Last week, Nisman, reading into the case of the attack, accused Kirchner and Timerman of conspiring to "ensure impunity" of Iranians, who had been indicted for participation in the blast by Argentinian authorities. In addition, Nisman asked the judge to question the president and foreign minister on the case and to impose an embargo on their property in the amount of 200 million pesos (about $23 million).
In addition, the prosecutor indicted several other politicians who are close to the incumbent government. He speculated that they were mediators in the negotiations with Iran on the exchange of Argentinian grain to Iranian oil. The government has rejected these accusations, calling the grain-for-oil deal unrealistic, according to the New York Times.
Argentina has accused a number of high-ranking Iranians, including former President Hashemi Rafsanjani and seven former government officials of having been involved in the organization of the largest terrorist attack in the country's history, which killed 85 people and injured over 200. Iranian authorities continue to vehemently deny the accusations.
