A rights group said the crackdown on protests has killed at least 734 people – but said the actual figure is likely in the thousands.

President Donald Trump called on Iranians today to keep protesting against their government and warned that those responsible for killing demonstrators would “pay a big price.”

Some 2,000 people have been killed in Iran since protests erupted at the end of last month, US-based activists said on Tuesday. An anonymous Iranian security official appeared to confirm the count.

Trump threatens "very strong action" against Iran if it executes protesters, amid rising international outrage over the crackdown.

In an interview with CBS News, the US President threatened “very strong action” if Iranian authorities go ahead with hangings of some protesters.

Iran protests that started over an economic crisis have turned into anti-regime protests, with demonstrators chanting anti-Khamenei slogans like Death to Khamenei and Death to the Dictator.

US President Donald Trump has told protesters in Iran that "help is on the way," as the death toll after more than two weeks of anti-government protests continues to increase, sparking a global outcry.
