Mahsa Amini, 22, from the Iranian Kurdish town of Saqez, was arrested this month in Tehran for "unsuitable attire" by the morality police that enforces the Islamic Republic's strict dress code for women.

Her death has sparked the first big show of opposition on Iran's streets since authorities crushed protests against a rise in gasoline prices in 2019.

"At least 83 people including children, are confirmed to have been killed in (the) #IranProtests," Iran Human Rights, a Norway-based group, said on Twitter.

Despite the growing death toll and a fierce crackdown by authorities, videos posted on Twitter showed demonstrators calling for the fall of the clerical establishment in Tehran, Qom, Rasht, Sanandaj, Masjed-i-Suleiman and other cities.

State television said police had arrested a large number of "rioters", without giving figures.

Meanwhile, Germany's foreign minister said on Thursday she wanted the European Union to impose sanctions on Iran following Amini's death.

In Norway, several people attempted to enter the Iranian embassy in Oslo during an angry demonstration in which two people sustained light injuries, Norwegian police said. Police detained 95 people, public broadcaster NRK reported.
