Iran's exiled Crown Prince issued a call for British and Western governments to protect their citizens from “violence perpetrated by supporters of the Iranian regime" after the latest attack in London.

Iranians in the UK, demonstrating against a memorial service for the late president Ebrahim Raisi on Friday were targeted by possible Iranian state agents, resulting in injuries to four people, as reported by the Metropolitan Police who confirmed the arrest of one suspect.

Prince Reza Pahlavi said, "What happened in London on Friday must not happen again," the latest in a string of incidents against dissidents in the UK since 2022.

Journalist and political activist Masih Alinejad who has also been the target of Iranian death threats through government agents in the UK and US, said the British authorities must act against the "thugs of the Islamic Republic."

In a show of defiance, Iranians in the UK rallied the following day in front of Iran's embassy in London to protest the violence. Pahlavi said, "Your coming together at this short notice to defend our compatriots is commendable," Pahlavi stated.

In March, Iran International host Pouria Zeraati, was stabbed by unknown attackers outside his home in London, suspected to be Iranian agents. In November 2022, threats were made against two of the channel's London-based journalists before the offices were forced to close temporarily last year after UK security services, MI5, said it could no longer guarantee the safety of Iran International staff.
