Former New York City mayor Rudy Giuliani has been injured in a car accident in the US state of New Hampshire, as reported by his security guard. Giuliani's vehicle was struck from behind while traveling on a highway, leading to serious injuries. The security guard, Michael Ragusa, stated that Giuliani was diagnosed with a fractured thoracic vertebra, numerous lacerations, and injuries to his left arm and lower leg. Known as 'America's Mayor' for his leadership during 9/11, Giuliani later became an adviser and personal lawyer to Donald Trump. The accident occurred shortly after he assisted an alleged victim of domestic violence who had flagged him down for help. Giuliani was noted to have contacted 911 immediately following the incident. Further updates are expected as local police are contacted for comments.
