Witnesses also said anti-government protests broke out at several universities in Tehran despite tight security.
In Berlin, tens of thousands of people demonstrated on Saturday in solidarity with the protest movement in Iran. According to the police, about 80,000 people took part in the rally. The organizers of the event initially expected 50,000 participants.
Participants held up Iranian flags and signs criticizing Iran's leaders, many with the tagline "Women, Life, Freedom" in both English and German.
