Eight men have been arrested by the Metropolitan Police in two unconnected but “significant” terrorism investigations.
In one operation on Saturday, counter-terror officers arrested five men – four of whom are Iranian nationals – as they swooped in on various locations around the country. All are in police custody.
The Met said the arrests related to a “suspected plot to target a specific premises”.
In an update shortly after midnight, the force said: “Officers have been in contact with the affected site to make them aware and provide relevant advice and support, but for operational reasons, we are not able to provide further information at this time.”
Commander Dominic Murphy, head of the Met’s Counter Terrorism Command, said: “Counter-terrorism policing, supported by police and colleagues from across the country, have conducted arrests in two really significant operations, both of which have been designed to keep the public safe from threats.
“There are several hundred officers and staff working on this investigation, and we will work very hard to ensure we understand the threats to the wider public.”
He refused to say if the plot was related to Israel, but described it as “certainly significant” and said “it is unusual for us to conduct this scale of activity”.
He also asked the public to “avoid speculation and some of the things that are being posted online”.
MI5 director general Ken McCallum said in October that the intelligence agency had responded to 20 “potentially lethal” Iran-backed plots since 2022. He warned of the risk of an “increase or broadening of Iranian state aggression in the UK”.

Children ‘petrified’ by armed police
Rochdale resident Kyle Warren, who witnessed one of the arrests at a neighbouring house, said his children had been playing in the garden when they came running into the house, saying a man in a mask had told them to go inside.
“Obviously, I was a bit worried,” Mr Warren told Sky News’ Lisa Dowd, and so he went into the garden to investigate.
“As we’ve come out, we just heard a massive bang, seen loads of police everywhere with guns, shouting at us to get inside the house.”
From upstairs in his house, he then heard “loads of shouting in the house” and saw a man being pulled out of the back of the house, “dragged down the side entry and thrown into all the bushes and then handcuffed”.
There were about 20 to 30 officers with guns, he believes.
“It’s just shocking, really. You don’t expect it on your doorstep.”
His daughters were “petrified… I don’t think they’ve ever seen a gun, so to see 20 masked men with guns running round was quite scary for them”.
Mr Warren, who only moved into his house a year ago, said he had “never really seen anyone going in or out” of the house and actually thought it was empty.
Arrests and searches around the country
The Met added officers were carrying out searches at a number of addresses in the Greater Manchester, London and Swindon areas in connection with the investigation.
It said those detained were:
• A 29-year-old man arrested in the Swindon area
• A 46-year-old man arrested in west London
• A 29-year-old man arrested in the Stockport area
• A 40-year-old man arrested in the Rochdale area
• A man whose age was not confirmed arrested in the Manchester area.

Terror arrests in separate investigation
Police also arrested three further Iranian nationals in London on Saturday as part of another, unrelated counter-terror investigation.
The suspects were detained under section 27 of the National Security Act 2023, which allows police to arrest those suspected of being “involved in foreign power threat activity”.

Home secretary Yvette Cooper said in a statement: “I want to thank the police and our security services for the action they have taken to keep our country safe.
“Protecting national security is the first duty of government and our police and security services have our strong support in their vital work.”
She added: “These are serious events that demonstrate the ongoing requirement to adapt our response to national security threats.”
Last year, the government placed the whole of the Iranian state – including its intelligence services – on the enhanced tier of the new foreign influence registration scheme.
It means anyone asked by Iran to carry out actions for the state must declare it, or face prison time.
