TEHRAN (Press Shia Agency) – The Iranian Parliament’s National Security and Foreign Policy Commission plans to convene a meeting later this week on a recent attack by members of an extremist religious cult on the country’s embassy in London, the spokesman for the commission said.

Hossein Naqavi Hosseini told Press Shia Agency on Monday that the commission is scheduled to hold the session on March 14 to look into the embassy attack and whether or not the British police’s failure to act promptly was deliberate.

Deputies of Iranian Foreign Minister Mohammad Javad Zarif would also attend the meeting, he added.

In the attack on Friday, four men dressed in black climbed on to a first-floor balcony of the building, took down the Iranian flag, and waved flags of their radical cult in an apparent protest against the Islamic Republic.

No one was hurt during the incident and the trespassers were arrested when they came down after around three hours. The four were detained for causing criminal damage and being unlawfully on diplomatic premises, a spokeswoman for London’s Metropolitan Police said.

Immediately after the incident was reported, Iran’s deputy foreign minister for political affairs, Abbas Araqchi, expressed the Islamic Republic of Iran’s strong protest to the British ambassador to Tehran and demanded that the UK police fully protect Iranian diplomats in London and immediately deal with the assailants.

Iran’s ambassador to Britain, Hamid Baeidnejad, tweeted that the assailants were “advocates of the Shirazi cult”.
