Milan, 13 January (LaPresse) – The editorial board of Iran International has estimated that at least 12,000 people were killed during the violent crackdown on protests in Iran, which took place mainly over two consecutive nights, Thursday and Friday, 8 and 9 January. If the figures are confirmed, this would be the largest massacre in Iran's contemporary history. Over the past two days, the editorial board of Iran International has examined information received from a source close to the Supreme National Security Council, two sources in the presidential office, reports from various sources within the Islamic Revolutionary Guard Corps in the cities of Mashhad, Kermanshah and Isfahan, eyewitness accounts and testimonies from relatives of the victims, field reports, data linked to medical centres and information provided by doctors and nurses in various cities.
