By Ian Drury PUBLISHED: 08:00 EST, 23 October 2013 | UPDATED: 02:06 EST, 24 October 2013 A Royal Marine sergeant was caught on camera ‘executing’ a severely injured Taliban prisoner before telling his comrades: ‘I’ve just broken the Geneva Convention,’ a court martial heard yesterday. As the insurgent lay stricken with horrendous wounds from a helicopter strike, the 37-year-old commando pointed his 9mm pistol at the man’s chest and pulled the trigger. Footage of the alleged cold-blooded killing in an Afghan cornfield was captured in graphic video inadvertently filmed by one of the Marines on a helmet-mounted camera.
