Pro-Palestinian activists break into RAF Brize Norton

A security review has been launched across UK military bases after pro-Palestinian activists broke into RAF Brize Norton and sprayed two military planes with red paint.

Prime Minister Sir Keir Starmer condemned the action as "disgraceful", saying it was an "act of vandalism".

Footage posted online by Palestine Action on Friday showed two people inside the Oxfordshire airbase in darkness, with one riding on a scooter up to an Airbus Voyager and spraying paint into its jet engine.

South East counter terrorism police later confirmed its specialist officers were investigating the incident alongside Thames Valley Police and the Ministry of Defence (MoD).

Downing Street said the incident had not blocked any planned aircraft movements or stopped any operations.

Defence Secretary John Healey said he was "really disturbed" by the incident and had ordered an investigation and the wider security review.

Palestine Action said the activists evaded security and claimed they had put the air-to-air refuelling tankers "out of service".

However, RAF engineers are assessing the damage and a defence source told the BBC they did not expect the incident to affect operations.

In a statement, a Palestine Action spokesperson said: "Despite publicly condemning the Israeli government, Britain continues to send military cargo, fly spy planes over Gaza and refuel US and Israeli fighter jets."

Counter-terror police said the incident happened in the early hours of Friday and added enquiries were "ongoing to establish the exact circumstances".

Thames Valley Police earlier said it had received a report about people gaining access to the base and causing criminal damage.

"Inquiries are ongoing to locate and arrest those responsible," the force said.

RAF Brize Norton serves as the hub for UK strategic air transport and refuelling, including flights to RAF Akrotiri in Cyprus. The air force has conducted reconnaissance flights over Gaza out of the Cyprus base.

The base is encircled by a large perimeter fence, with security camera and sensors in the area in addition to manned security checkpoints. Patrols around the base are also carried out from time to time.

But a defence source said these measures would not have been able to provide complete cover around the large airbase.

Palestine Action has engaged in similar activity since the start of the current war in Gaza, predominantly targeting arms companies. In May, it claimed responsibility for the daubing of a US military plane in Ireland.

The group said the activists who entered RAF Brize Norton used repurposed fire extinguishers to spray red paint into the planes engines.

It also said they caused "further damage" using crowbars - though this is not visible in the bodycam footage it provided.

Video shows the activists then roaming around the airbase.

The protesters did not spray paint on the Vespina aircraft - used by the prime minister for international travel - which was also on the base.

The MoD told the BBC that RAF Voyager aircraft had not been involved in refuelling or supporting Israeli Air Force jets.

A spokesman said Voyagers have been used in the Middle East to refuel RAF Typhoon jets involved in the ongoing international efforts to tackle the so-called Islamic State group in eastern Iraq and Syria.

They have also been used in the Red Sea in the past in operations against Yemens Houthi rebels.

Lord West, Labour minister for UK security and former head of the Royal Navy, said earlier that while he was not aware of the full details, the break-in was "extremely worrying".

"We cant allow thing like this to happen at all," he told BBC Radio 4s Today programme, adding that breaches like it were "really a problem" for national security.

Conservative leader Kemi Badenoch said the security breach was "deeply concerning".

"This is not lawful protest, it is politically motivated criminality," she said in a statement.

"We must stop tolerating terrorist or extremist groups that seek to undermine our society."

Greg Bagwell - a former RAF deputy commander - said that in targeting the Voyager, the activists picked "a strange target".

Air Marshall Bagwell, now a distinguished fellow at the Royal United Services Institute (Rusi), told the BBC "those aircraft do not do what these protesters think they do. Theyre largely used for moving passengers or fuel".

He added that Voyagers had "the wrong connectors" that would stop them being used to help refuel Israeli or US jets, as the action group suggested.

But he said if the activists "wanted to create an effect, theyve clearly done that".

Shadow armed forces minister Mark Francois told the BBC any attempt to interfere with the engines of large aircraft was "totally reprehensible".

He added there were "serious questions for the MoD to answer" about how protesters were able to "gain access to what is supposed to be a secure RAF airbase".

The local Liberal Democrat MP Charlie Maynard described the activists actions as "stupid and dangerous".

He said the investigations should establish "how this happened and what can be done in future to make sure no further breaches occur".
