Argentine Judge Who Accused Officials of Covering Up Iran Role in 1994 Attack Dies Michael Lipin Argentinian judicial authorities seeking to prosecute officials suspected of covering up Iran's alleged role in a 1994 Buenos Aires terrorist attack have suffered another setback with the death of a judge who led the legal battle against those officials. Judge Claudio Bonadio, head of Argentina's No.11 Federal Criminal and Correctional Court, died Tuesday at the age of 64, after undergoing surgery for a brain tumor last year. Bonadio had spent years building a case against Argentinian officials who approved a controversial 2013 memorandum of understanding (MOU) with Iran. He had gathered evidence alleging the MOU was part of an illicit deal for Buenos Aires to shield Iranian suspects in the 1994 attack from justice in return for securing oil and other economic benefits from Tehran. .
