The expected indictment against the Israelis at the center of the serious espionage case for Iran could be severe due to the long period during which the suspects allegedly operated on behalf of Tehran. Charges against the suspects have already been determined and the indictment is set to be filed on Friday. In the past, severe espionage charges were brought against Israeli atomic technician Mordechai Vanunu, who leaked information and photos from the nuclear reactor in Dimona.
