Watch: BBC looks at how activists breached RAF base 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.

The BBC's Phil Mackie visited the air base to look at security around its perimeter fence.

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

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