Last Wednesday, Argentine prosecutor Alberto Nisman accused Iran of "infiltrating" South America and establishing intelligence networks aimed at carrying out more terrorist attacks in the region. Nisman said the effort has been ongoing since the 1980s in Brazil, Paraguay, Uruguay, Chile, Colombia, Guyana, Surinam and Trinidad and Tobago. "These are sleeper cells," he explained. "They have activities you wouldn't imagine. Sometimes they die having never received the order to attack."
