Four people have been charged after an investigation into £7million worth of damage was caused to two Voyager aircraft at RAF Brize Norton.

The alleged offenders, aged between 22 and 36, have been charged with conspiracy to enter a prohibited place knowingly for a purpose prejudicial to the safety or interests of the UK and conspiracy to commit criminal damage.

The incident, which occurred on June 20 and is under investigation by Counter Terrorism Policing South East, saw the turbines of the two aircraft sprayed with red paint.

Amy Gardiner-Gibson, 29, Daniel Jeronymides-Norie, 35, Jony Cink, 24, and Lewie Chiaramello, 22, will appear at Westminster Magistrates' Court later today.

Palestine Action damaged two military aircraft last week

Activist group Palestine Action claimed credit for last month's incident at RAF Brize Norton in Oxfordshire.

On Wednesday, MPs passed legislation to proscribe the group as a terrorist organisation, with 385 MPs voting in favour, while only 26 were against.

Before it becomes law, the motion is expected to be debated and voted on by the House of Lords on Thursday.

The ban would make membership or inviting support of the group a criminal offence under the Terrorism Act, carrying a maximum sentence of 14 years in prison, if passed.

Last week, a 41-year-old woman was arrested on suspicion of assisting an offender and was later released on bail until September 19.

A 23-year-old man detained on Saturday was also released without charge.

Palestine Action previously posted footage online showing people inside the Oxfordshire base.

One protester appeared to ride an electric scooter up to an Airbus Voyager air-to-air refuelling tanker, before spray-painting it on the jet engine.

Dan Jarvis, the security minister, told MPs the attack at RAF Brize Norton 'was just the latest episode in Palestine Action’s long history of harmful activity'

Palestine Action has staged demonstrations that have included spraying the London offices of Allianz Insurance with red paint and vandalising US President Donald Trump’s Turnberry golf course in South Ayrshire.

Dan Jarvis, the security minister, told MPs the attack at RAF Brize Norton "was just the latest episode in Palestine Action’s long history of harmful activity”.

He said: “Palestine Action has orchestrated a nationwide campaign of property damage featuring attacks that have resulted in serious damage to property and crossed the threshold from direct criminal action into terrorism.”

Jarvis added: "Palestine Action is not a legitimate protest group. People engaged in lawful protest don’t need weapons. People engaged in lawful protest do not throw smoke bombs and fire pyrotechnics around innocent members of the public. And people engaged in lawful protest do not cause millions of pounds of damage to national security infrastructure, including submarines and defence equipment for Nato.”
