More details emerge from the mayhem today:
The reformist website, Rah-e Sabz, reported that an elderly man was among the dead after being shot in the forehead in Valiasr crossroads in Tehran city centre. Three others were said to have been shot nearby at Kalej Bridge in Enghelab Street. Rah-e Sabz, citing witnesses, said crowds held up the elderly man and started chanting slogans against Iran's supreme leader, Ayatollah Ali Khamenei.
Crowds also prevented security forces from taking away those wounded in the shootings. According to other eyewitness reports, members of the hardline Basij militia attacked demonstrators with daggers and knives. Disturbances were also reported in Isfahan and Najafabad, where the Rah-e Sabz described the situation as "severe".
