The United Nations has called on Iran to respect its citizens' right to peaceful protests amid reports of the use of force to quell protests over the past three days.
A statement from Farhan Haq, spokesman for UN Secretary-General Antonio Guterres said, "We reaffirm, as we do with all these protests, that the rights of freedom of expression and peaceful protests must be respected by all including the security forces".
But he declined to comment whether Guterres was in contact with Iranian authorities over the protests.
Popular protests have erupted in Iran against hiking prices, the collapse of the local currency and the poor basic services. The protesters chanted against Ali Khamenei and other clerical leaders.
A video of Tehran protests showed demonstrators chanting "Death to Khamenei," while one shouted that the Basij militia were attacking people.
The protests erupted in Isfahan, Shiraz and Shahin Shahr, Karaj, Mashhad, Sari, Zarak, Rasht and Ahvaz amid violent clashes with police and security forces.
