argentina suffered a terrorist attack in 1994, the amia bombing targeting a buenos aires jewish center, that killed 85 people and wounded 300. the investigation remained open for years, and prosecutor alberto nisman was appointed to the case. he accused iran of organizing the attack, and the hezbollah group of carrying it out. he intended to prosecute five iranian officials, including former iranian president akbar hashemi rafsanjani, but argentina signed a memorandum of understanding with iran for a joint investigation. nisman accused the president of signing that memorandum for oil and trade benefits, according to hundreds of hours of wiretaps. on 19 january 2015, he was found dead at his home, a day before a congressional hearing to explain his accusation, which caused a great controversy. as of 2016, both the cases of the amia bombing and the death of nisman remain unresolved, and the courts declined at the time to investigate his denunciation of kirchner.
