The investigation continues into the death of prosecutor Alberto Nisman, who was investigating the 1994 terror bombing of the Argentine Jewish Mutual Assistance Association. It is still unclear whether Nisman's death was a suicide, induced suicide, or homicide. Further questions have arisen concerning Nisman's contact with Western spy agencies. Former Argentine intelligence agency chief Jaime Stiuso exchanged phone calls with Nisman before the prosecutor's death and will be called to testify. Leonel Poblete reports from Buenos Aires. teleSUR
