Iran summoned the British ambassador in Tehran after anti‑Iranian protesters in London climbed the balcony of Iran’s embassy, pulled down the national flag, and replaced it with another symbol, which is a serious violation of diplomatic norms.

Why it matters:

Iran views the incident as a breach of the U.K.’s obligations to protect diplomatic missions under the Vienna Convention.

Tehran also says certain London‑based Persian‑language media outlets have been encouraging unrest inside Iran, calling their activities a form of hostile interference.

What happened:

Anti‑government activists in London removed the Iranian flag from the embassy building and replaced it with a pre‑revolution emblem.

Iran’s Foreign Ministry summoned U.K. Ambassador Hugo Shorter to formally deliver a strong protest.

Alireza Yousefi, Director‑General for Western Europe at Iran’s Foreign Ministry, condemned the “failure of British police” to protect the embassy and prevent unlawful actions.

He also objected to the continued operation of Persian‑language media outlets in London that have been spreading disinformation and promoting violence.

Big picture:

Iran has repeatedly criticized Western governments for political and media support for anti‑government protests.

The U.K. hosts several major Persian‑language broadcasters, including outlets frequently fueling unrest.

Diplomatic tensions have escalated as riots inside Iran continue and anti-Iran groups intensify their activities abroad.

What they’re saying

Iranian officials stressed that the U.K. is legally responsible for ensuring the safety of Iranian diplomats and facilities.

The British ambassador expressed regret over the incident and said he would report the matter to London “as soon as possible.”
