Exiled opposition leader Reza Pahlavi, son of Iran’s deposed Shah Mohammad Reza Pahlavi, praised the ongoing protests in Iran on Friday and called for larger demonstrations over the weekend. In a social media video message, he urged Iranians to move beyond street rallies and organize to seize and hold city centers. Pahlavi said he was preparing to return to Iran, believing that change was now very close.

Human rights activists warned that the Iranian government might shut down the internet to conceal its crackdown. According to the Norway-based Iran Human Rights organization, at least 51 people have been killed so far. Nobel Peace Prize laureate Shirin Ebadi cautioned that security forces could prepare for mass killings under communication blackouts.

Supreme Leader Ayatollah Ali Khamenei denounced the protesters as vandals and insisted the Islamic Republic would not retreat, blaming the United States for the unrest. U.S. President Donald Trump mentioned possible new military actions against Iran, further heightening tensions.
