Iran is ready to consider compromises to reach a nuclear deal with the United States if Washington is willing to discuss lifting sanctions, Iran's Deputy Foreign Minister Majid Takht-Ravanchi told the BBC.
Iran has said it is prepared to discuss curbs on its nuclear programme in return for the lifting of sanctions, but has repeatedly ruled out linking the issue to its ballistic missiles and other conventional weapons.
US envoys Steve Witkoff and Jared Kushner will meet with Iranian officials on Tuesday.
A day after US President Donald Trump advocated for regime change in Iran, the new generation of revolutionaries were out in force.
In Munich, Germany, Iranian supporters of Reza Pahlavi, the son of the former Shah, raise a giant flag of pre-Islamic revolution Iran.
Pahlav Supporter Daniyal Mohtashamian said: "Well, we came here because the people in Iran are fighting for freedom, and there were like huge protests."
An Israeli flag is seen in the background, with Israel's intelligence agency Mossad admitting that they were working on the ground in Iran during the recent protests.
These demonstrations are coinciding with the Munich Security Conference in which top defence officials from most of the major countries have gathered to discuss various issues.
Iranians living In Bucharest, Romania protest outside the Iranian Embassy calling for regime change, saying the government is executing hundreds of young people every week.
Iran's atomic chief said on Monday that Tehran coul agree to dilute its most highly enriched uranium in exchange for all financial sanctions being lifted.
However, Iran is unwilling to accept zero uranium enrichment, which had been a key impediment to reaching a deal last year.
The US views enrichment inside Iran as a pathway to nuclear weapons, which Iran denies seeking.
During his first term in office, Trump pulled the US out of a 2015 Iran nuclear agreement, which eased sanctions on Iran in exchange for Tehran limiting its nuclear programme to prevent it from building an atomic weapon.
Trump is sending more military vessels to the region, threatening to launch strikes against Iran if talks fail.
Pahlavi, whose father's infamous SAVAK security force was said to have tortured and executed political opponents, urged Trump to destroy the regime of Ayatollah Ali Khamanei.
Reza Pahlavi, son of former Shah of Iran said: "The importance of a strike to neutralise the regime forces of repression is the element that could get people back into the streets to continue their struggle. That's the element that pretty much is at stake right now, which is why Iranians in Iran and abroad are waiting impatiently that this happens faster and sooner rather than delaying it."
