A protester scaled the Iranian Embassy in London on Friday, removing the Islamic Republic's flag and replacing it with the pre-1979 "Lion and Sun" emblem, linked to Iran's monarchy. Videos shared online show a crowd cheering the act. London's Metropolitan Police responded, arresting two individuals on suspicion of aggravated trespass and assault, and are seeking a third. This incident occurs amid ongoing widespread protests within Iran against the current regime, which have seen significant detentions and casualties.
