A new wave of anti-regime protests has broken out in Iran, according to footage circulating online.
Clips taken in Tehran, as well as the smaller cities of Shiraz and Arak, reportedly show demonstrators chanting for the fall of the Ayatollah.
"Death to the dictator" and "long live the Shah" were among the slogans shouted from residential windows, according to Iran International.
The apparent resurgence of protests marks the first display of open dissent by the Iranian people since a spate of mass anti-government demonstrations, which started in December following an economic collapse, were brutally suppressed by security forces.
At least 6,000 people are known to have died during the crackdown, with some human rights groups estimating the total may have reached tens of thousands.
The new protests broke out amid a series of gatherings internationally in solidarity with Iranians.
One event in Munich on Saturday reportedly attracted more than 250,000 people and was addressed by Reza Pahlavi, the son of the last Shah.
This all comes against the backdrop of ongoing US-Iran negotiations to avert military intervention by the Americans, which have yet to yield a diplomatic settlement.
Key sticking points are understood to include the level of Tehran's nuclear enrichment, its ballistic missile capability, and its support for regional proxies like Hamas and Hezbollah.
Iranian officials have reportedly offered to dilute their stock of enriched uranium, but have ruled out a complete moratorium on enrichment and any restrictions on their missile programme.
Upping the pressure on Tehran, President Trump has ordered the world’s largest aircraft carrier, the USS Gerald R Ford, to transfer to the region, backing up the “armada” he sent to the Gulf last month.
It will join the USS Abraham Lincoln within striking distance of Iranian territory, with Trump saying on Thursday that the results of a failure to reach a deal would be “very traumatic”.
"It should happen quickly. They should agree very quickly,” he added.
