Anti-Israel activists broke into a Royal Air Force base in central England on Friday, where they damaged and sprayed red paint over two military aircraft used for refueling and transportation.

The campaign group Palestine Action said two of its activists had entered the Brize Norton base in Oxfordshire, spraying paint into the engines of the Voyager aircraft and causing further damage with crowbars.

“Despite publicly condemning the Israeli government, Britain continues to send military cargo, fly spy planes over Gaza and refuel U.S./Israeli fighter jets,” the group wrote in a statement, posting a video of the incident on X.

“Britain isn’t just complicit, it’s an active participant in the Gaza genocide and war crimes across the Middle East.”

Britain’s defense ministry condemned the “vandalism” and said it was working with police to investigate.

“Our Armed Forces represent the very best of Britain. They put their lives on the line for us, and their display of duty, dedication and selfless personal sacrifice are an inspiration to us all,” it said.

“It is our responsibility to support those who defend us.”

Police said they were investigating a report of people gaining access to the air base and causing criminal damage.

Palestine Action is among groups that have regularly targeted defense firms and other companies in Britain linked to Israel since the start of the conflict in Gaza.

The group said it had also sprayed paint on the runway and left a Palestine flag there.

In November, the group stole busts of Israel’s first president, Chaim Weizmann, from the University of Manchester.

The UK defense ministry said in December 2023 that it would conduct surveillance flights over Gaza to aid in hostage recovery efforts following the Hamas-led October 7, 2023, assault in southern Israel, in which some 1,200 people when killed and 251 were taken hostage.

It denied at the time that it was carrying out the flights for any other purpose, and stressed that the surveillance aircraft would be “unarmed, do not have a combat role, and will be tasked solely to locate hostages.”

The flights are said to have continued until now, and UK Defense Secretary John Healey reiterated to investigative journalism group Declassified UK last week that the only intelligence passed on to Israel from the surveillance flights is “linked to finding and helping freed hostages.”

Anti-Israel sentiment has skyrocketed globally since October 7, 2023.
