Fernandez blames prosecutor's death on "sordid" conspiracy.

Buenos Aires, Jan 20 (EFE).- Argentinian President Cristina Fernandez blames a "sordid" conspiracy for the death of special prosecutor Alberto Nisman before he could testify to Congress about his probe into the 1994 terror attack on a Jewish center which he said Fernandez and other senior officials helped cover up.

In a long letter posted Monday on her social networking page, Fernandez slammed attempts to create "diversions and lies, cover ups and confusion" about the attack on the AMIA Jewish social center in which 85 people died, and said they were being orchestrated by rogue intelligence agents and her own media opponents.

The Argentinian president asked why the prosecutor would ask for a gun from one of his aides for self-defense when he had 10 police officers protecting him and was living in a building with private security.

"Regarding the suicide? of the prosecutor assigned to the AMIA case, we are left with not just shock and unanswered questions but also a story that is already far too long, far too tedious, far too hard to take, but above all, very, very sordid," Fernandez wrote.

"And that is the tragedy of the worst terror attack that has ever occurred in Argentina," Fernandez said.

She added that the key to finding out who was responsible for the Jul. 18, 1994 car bomb massacre is to go after the ones responsible for the cover-up, since they are identical.

"I believe we, the Argentinian people, do not deserve to have our intelligence underestimated in this way and that is especially the case when there are 85 victims and their families who have been waiting 21 years for justice to be done," the Argentinian president concluded.

Before he was found with a bullet in his head on Sunday, Nisman claimed to have proof implicating Fernandez, her predecessor in the presidency Carlos Menem, current foreign minister Hector Timerman, plus the judge at the original trial and several senior officers of the intelligence services in the cover-up.

Nisman, 51, who had been at the front of the Investigation Unit assigned to the AMIA bombing since 2004, claimed to have finally secured evidence proving that Iran and the Hezbollah organization were behind the planning and execution of the attack.

The prosecutor filed a suit last week against Fernandez and several of her associates for signing an agreement with Iran that allegedly allowed the suspects in the bombing of the Jewish institution to go free in return for trade and other concessions.
