Police have arrested four masked protesters after they stormed the first-floor balcony of the Iranian embassy in London and waved flags.
The four were arrested on suspicion of causing criminal damage and being unlawfully on diplomatic premises, a spokeswoman for London's Metropolitan Police said.
No one was hurt during the incident, believed to be an apparent protest against the government in Tehran, and the four were arrested when they came down voluntarily after around three hours.
In 1980, gunmen seized the embassy to try to secure the release of Iranian political prisoners. One hostage was killed in the six-day siege, and another died when British commandos stormed the building, killing all but one of the gunmen.
