Tensions between the governments of Iran and Great Britain increased after the security incident in Perford.

After the British Prime Minister's speech in Parliament, Iran's Foreign Ministry strongly condemned the "baseless accusations" of the British government.

Before that, the British Foreign Office said on Monday morning that Ali Mousavi, Iran's ambassador in London, was summoned and in his statement imposed sanctions on two Iranians.

One of the two sanctions, Rohullah Bazakandi, head of the counter-espionage operation of the Revolutionary Guards, was introduced for "representing the regime with a clear intention to threaten, plan and carry out a ground attack outside Iran."

Andy Burnham told the British Parliament that "it is likely that the incident was coordinated in Iran and almost certainly directed by the Revolutionary Guards."
