Six guests and a guide were on a drive in Kafue National Park when the incident happened. The woman was taken by helicopter to a hospital in South Africa with injuries and was later declared dead. Four other people received treatment for minor injuries.A video of the elephant attack, apparently filmed by one of the tourists, was shared online. The animal is seen chasing the car – when the vehicle stopped, the elephant flipped it over.
