Bungling defence chiefs were warned about the threat of disruption at RAF Brize Norton less than three weeks ago but failed to shore up the crucial base's defences.

Armed Forces top brass were said to be left speechless after pro-Palestinian supporters entered the base unopposed and sprayed red paint into the engines of RAF Voyager aircraft.

Shocking footage shared by the group Palestinian Action showed protesters storming across the RAF runway in Oxfordshire on electric scooters.

Bodycam images then show them spraying red paint into the turbine engines of the air-to-air refuelling tankers which the RAF say are 'vital for enhancing the operational reach and flexibility of Britain's military air power'.

But the recent Strategic Defence Review (SDR) published earlier this month warned about the danger of 'disruption' to RAF Brize Norton, with the logistic supply line being targeted.
