MI5 Chief Warns of Growing Iranian Threats to UK Military Bases
“Iran is stepping up attempts to hit harder targets such as military sites in Britain.”
A day after Prime Minister Andy Burnham told Parliament there were “strong indications” that Iran is behind a foiled terror attack on a southern England airbase, MI5 chief Ken McCallum warned that Tehran is actively targeting British military sites.
The warning from the chief of the country’s domestic intelligence agency comes after five British nationals were arrested near the Fairford airbase, which hosts the U.S. military’s B-1 and B-52 long-range bombers. Most of the suspects involved in one of the most alarming terrorist threats in the country’s recent history were “released on bail under strict conditions,” the BBC confirmed.
More than 50 arrests have been made in the UK over the past 12 months in Iran-linked operations, MI5 Director General Ken McCallum said on Tuesday, warning that Tehran had expanded its “hybrid campaign” and was now going after “harder targets like military sites.”

MI5 chief Ken McCallum disclosed that the Iranian regime has ramped up terrorist activities aimed at British military sites. “Iran is stepping up attempts to hit harder targets such as military sites in Britain…, the UK’s domestic spy chief said on Tuesday,” Reuters reported.
“McCallum said he could not speak about the Fairford incident because of an ongoing investigation, but he said there had been a major shift this year in ‘Iranian ambitions to come at harder targets, like military sites’,” the news agency added. “McCallum said over the past year Iran-linked operations had led to more than 50 arrests.”
The Associated Press reported:
Iran is trying to hit military sites in Britain and the suspected plot to attack a U.S.-run military air base in September is “not unique,” the head of the MI5 spy agency said Tuesday, as he warned that both Tehran and Moscow are expanding their attacks against the U.K.
Ken McCallum, who leads the U.K.’s domestic security service, said Tehran is seeking to intensify its attacks in Britain beyond the traditional targets of Iranians opposed to the country’s Islamic authorities.
That has included arson and sabotage attacks on Jewish sites that Britain says were carried out by Iranian proxies.
McCallum said another “major shift this year has been Iranian ambitions to come at harder targets, like military sites.”
The incident at RAF Fairford “is not unique. There have been other examples, not just in the U.K. but around the world,” McCallum said. (…)
Seven men in their 20s have been arrested and released on bail under investigation. In all, more than 50 people have been arrested over Iran-linked plots in the past year, McCallum said.
According to the British government, Iran’s Islamic Guard (IRGC) terrorist group most likely targeted the Fairford airbase.
“I can confirm our assessment that it is highly likely to have been coordinated in Iran, almost certainly directed by Iran’s Islamic Revolutionary Guard (IRGC),” Prime Minister Andy Burnham told the UK House of Commons on Monday. “We will not tolerate these threats on our soil.”
“We will crack down on Iran’s use of criminal networks, using our full range of powers to target them and their funding streams, and we will bring further sanctions to restrict the capacity of Iran and the IRGC to do us harm,” he added.

Israeli intel foiled attack on UK airbase
The Iranian terror attack on the airbase was likely foiled thanks to Israeli intelligence. Prime Minister Benjamin Netanyahu told Fox News on September 30 that Israel had warned Britain of the impending attack.
While the Burnham-led Labour government released the suspected Iranian terrorist cell on bail, it slapped sanctions on Israel the very next day.
“You talked about the thing in Britain,” Netanyahu said, referring to the foiled attack.
“Do you want to hear how absurd things are there and how far the anti-Israeli propaganda has gone?” he added. “We gave the Brits the intel that there was going to be an attack, and it’s an Iranian-sponsored attack, and pretty much the next day they slapped sanctions on us. On us.”

And then they go let potential terrorist suspects go on bail WHILE a guy who slashed a dinghy in French waters has bail denied and the book thrown at him 🙄
A little late there, buddy, a little late.
To quote the Beatle song, “Good Morning, Good Morning,” parliament!
“the head of the MI5 spy agency said Tuesday, as he warned that both Tehran and Moscow are expanding their attacks against the U.K.” Allow yourselves to become as weak and overrun with Muslims and this was bound to happen.
Britain has become a ridiculous nation.
We are not far behind, letting Muslims by millions in our coutand foreign countries to buy our very land
We are not far behind because the Left (socialists, Islamists, communists, progs) are doing everything they can to force accommodation of those who want to destroy us. Accommodating AND accepting the enemy within is suicide, plain and simple.
When push comes to shove, at least we’re armed so we can kill what needs killing.
Much to the democrat’s frustration.
M must be rolling over in his grave. A pasty faced simp who overdosed on hairspray has taken his seat.
MI5 is domestic. International is MI6.
He sure looks tame and domesticated.
Perhaps the Brits ought to pay attention (then protect) some of the brave young British females who want nightmare of Muslim Male Invasion to stop! Send them back. So far, England could make this decision – they are not part of the European Union.
Get a move on it – threefold:
1 – stop accepting the boat people – arm your border and send them back across the water
2 – Train your military to resist, NOW
3 – Replace the brainwashing of your police and arm them. Time for being nice, welcoming and understanding to a “tribe” that wants to force submission and degrading and enslaving of their wives is over. Denying education to females older than 8 and beheading or shooting females with whom those in power disagree – probably over anything must stop. There are some VERY ugly videos on the I’net now. Watch and wise up, FAST England (and the rest of western Europe).
Why do you think Trump pulled his bombers out of the UK air base?
The UK military is a bad joke at this point.
He needs to go further: pull out the nuclear warheads. We have leased to the British government.
“MI5 chief Ken McCallum warned that Tehran is actively targeting British military sites.”
Oh dear!
Has he taken it up with his boss — Shabana Mahmood?
🇬🇧🤡
3100 miles is the distance between UK and Iran and it is an insufficient buffer to protect our forces in the UK. Pull them out. Pull them all out. I’m not sure where in Europe I would consider posting them so pull them all out.
They cannot protect their bases without interfering with Muslims. So therefore their bases are freefire zones.
Subotai Bahadur
They tried to mock Trump for removing the bombers, remember?
Sadly, Britain is circling the drain.
Britain is already beyond the Schwarzschild radius
At least that’s how Larry Schwarzschild, our plumber, explains it.
Bases? How about your entire country? Every organization in GB is infiltrated with muslims and it is no mystery what they plan to do with your country!
If the millions of muslims infesting the UK were to go “Oct. 7th” on the Nation who would stop them? Are the British (and US) so ignorant that they don’t think those mosques are NOT ARSENALS? You can bet your last pence that everyone of them has a “hidden room” that is stocked with weapons. Crap, they have enough cutlery in their kitchens to overtake the UK by force! I keep asking “WHEN is ENOUGH – ENOUGH”? When will civilized Nations return the muslims to muslim Nations or at least demand they conduct themselves as citizens of the civilized Nation they infest? I’m old – will probably never see it, but I fully expect the next “World War” to be civilization vs muslim!
Man, I have been saying that for well over a decade, which is why that they won’t allow you to get with in a mile of a mosque with a search warrant if the entirety of both Congress of Senate depended on it. They are totally protected, for some insane reason.
Just now noticed that threat, huh? Slow horses in real life.
