Protests flared again across Iran on Friday night despite a sweeping security crackdown and a nationwide internet blackout. This is now the 13th night of protests. Verified videos published by AFP showed large crowds gathering in Tehran, including in the Sadatabad district, where demonstrators banged pots and chanted slogans against Supreme Leader Ayatollah Ali Khamenei. In Washington, U.S. President Donald Trump said Iran was in “big trouble,” warning authorities, “you better not start shooting because we’ll start shooting too.”
