Iran pre-Islamic revolution flag was briefly hoisted on the Iranian embassy in London. A video going viral on social media shows a man climbing up the building as he tears down the Iranian regime flag and replaces it with the pre-1979 flag with a lion and sun during a demonstration on Saturday.Hundreds of other protestors gathered outside the building were also seen waving the pre-Islamic revolution flag, chanting anti-government slogans.The flag stayed in place for several minutes before being removed, news agency AFP reported.Fresh protests also flared across Iran on Friday, in Tehran, Mashhad, Tabriz and the holy city of Qom, chanting slogans against Supreme Leader Ayatollah Ali Khamenei. In Tehran’s Sa’adat Abad district, residents banged pots and pans and blared car horns in a show of defiance, undercutting state media assertions that calm had returned.The demonstrations, described as the biggest since the 2022–23 unrest triggered by Mahsa Amini’s death in custody, began on December 28 amid soaring living costs and the rial’s plunge, and have since shifted into open challenges to Iran’s clerical system.
