Four men have been arrested after they stormed the first-floor balcony of the Iranian embassy in London and apparently took down the Iranian flag - writes standard.co.uk.
The men, dressed all in black, stood waving blue and white flags for around two hours.
Scotland Yard said the protesters were arrested on suspicion of causing criminal damage and being unlawfully on diplomatic premises.
It is understood they did not enter the building itself.
Images posted on social media showed four men on the balcony of the embassy, waving the flags.
The Met’s Taskforce were called to assist police in Westminster, and were pictured usinga "cherry picker" platform to reach the men.
Iran's ambassador to Britain, Hamid Baeidnejad, tweeted that the men were "advocates of the Shirazi cult" and had replaced Iran's national flag with that of their group, according to Reuters. He said all staff at the embassy were safe.
The group were allegedly demanding the release of the recently detained son of religious figure Grand Ayatollah Sadegh Hossein Shirazi, BBC Persian reported.
A spokesman for the Met said: “Police were called at 4.20pm on Friday, March 9, to reports of four protestors on the balcony of the Iranian Embassy in Princes Gate, Knightsbridge.
“At around 6.40pm, all four were arrested on suspicion of criminal damage and being unlawfully on diplomatic premises.
