Multiple channels of Iran's state television broadcast images on Thursday showing the leaders of an exiled dissident group and a graphic calling for the death of the country's supreme leader, an incident that authorities described as a hack.
For several seconds, graphics flashed on screen, interrupting the broadcast to depict the leaders of the opposition Mujahideen Khalq Organization (MKO), Maryam and Masoud Rajavi. A man's voice could be heard chanting "Salute to Rajavi, death to (Iranian Supreme Leader Ali) Khamenei!", according to videos posted on social media.
