Iranians, with woman ripping off their hijabs, have staged new protests denouncing the country's theocratic regime in defiance of a crackdown that is now seeing those arrested put on trial and facing the death penalty.
The street rage was sparked by the death in September of Mahsa Amini who had been arrested by the Tehran morality police.
Norway-based Iran Human Rights (IHR) group said that students on Tuesday staged a sit-in protest at Isfahan University while social media footage indicated a similar action was in progress at the engineering faculty of Amir Kabir university in Tehran.
The Norway-based Hengaw rights organisation said the funeral in the mainly Kurdish city of Sanandaj in northwestern Iran on Monday for Sarina Saedi, a 16-year-old girl it said was killed in the crackdown, turned into a protest with anti-regime slogans shouted and women removing headscarves.
Residents of the Tehran district of Ekbatan late Monday shouted protest movement slogans including "Death to the dictator" with security forces using stun grenades in a bid to stop the action, according to footage posted on the 1500tasvir monitoring site and other outlets.
Images shared on social media showed murals of revolutionary leader Ayatollah Ali Khamenei and his predecessor Ayatollah Ruhollah Khomeini had been daubed with red paint in the holy city of Qom.
The protests have also seen a myriad of different tactics, with observers noting a new trend of young people tipping off the turbans of clerics in the street.
According to IHR, 160 people have been killed in the crackdown on the protests sparked by Amini's death and another 93 in a distinct protest wave in Zahedan in the southeastern Sistan-Baluchistan province.
IHR has warned that these figures are a minimum, with information slow to flow in due to disruptions of the internet by the authorities.
