Thousands of opponents to Iran's authorities rallied in Paris on Saturday, joined by Ukrainians to call for the fall of the government in Tehran, hopeful that U.S. President Donald Trump's 'maximum pressure' campaign could lead to change in the country.

The protest, organised by the Paris-based National Council of Resistance of Iran (NCRI), which is banned in Iran, comes as two of the group's members face imminent execution with a further six sentenced to death in November.

"We say your demise has arrived. With or without negotiations, with or without nuclear weapons, uprising and overthrow await you," NCRI President-elect Maryam Rajavi said in a speech.
People from across Europe, often bussed in for the event, waved Iranian flags and chanted anti-government slogans amid images deriding Iran's Supreme Leader Ali Khamenei.

Hundreds of Ukrainians accusing Iran of backing Russian President Vladimir Putin in the war against Ukraine joined the protest.
