Nine more people have been killed overnight as clashes between protesters and security forces continue for a sixth day.
According to state media the latest violence, in the central Isfahan region, brought the number of reported deaths to at least 22.
The protest began last Thursday in the city of Mashhad, initially against price rise and corruption, but have since spread amid wider anti-government sentiment. Some protesters chanted slogans against the government and the supreme leader Ayatollah Ali Khamenei.
Hundreds of people have been arrested. President Hassan Rouhani said protests were an opportunity, not a threat, but vowed to crack down on lawbreakers.
Meanwhile, US President Donald Trump has said, it is time for a change in Iran. He said in a tweet that Iran is failing at every level despite what he called a terrible deal made with them by the administration of his predecessor Barack Obama.
