65-year-old Reza Pahlavi, the exiled son of Iran’s last shah has become a prominent voice calling for continued protests in the country.
Human rights groups say at least 2,500 people have been killed in two weeks, as the authoritarian regime tries to quell the demonstrations.
Meanwhile, US President Donald Trump did not rule out military action against the country due to its violent suppression.
But who is Pahlavi, and what support does he enjoy among Iranians?
