American tourist, 80, killed by charging elephant during safari tour at Kafue National Park in Zambia

​​​​​​​An 80-year-old American tourist was killed by a bull elephant when the safari tour group she was part of was charged at by the animal.

Another female guest was also injured in the incident that took place in the Kafue National Park, Zambia.

The group of six guests and a guide had been on a safari from Lufupa Camp, when around 9.30am local time on Saturday 30 March, their vehicle was "unexpectedly charged" by the animal.

A video captured the terrifying moment the elephant chased down the tour group.

The group's vehicle was driving through the national park as the elephant could be seen closing in on them.

The vehicle came to a stop and in the moments before the elephant knocked it over, the guide could be heard shouting "hey, hey, hey, hey, hey, hey!"

People were heard screaming during the attack.

The second guest who suffered an injury was rushed to a private medical facility, while the other four guests received treatment for minor injuries.

Keith Vincent, Wilderness chief executive officer, said: "This is a tragic event and we extend our deepest condolences to the family of the guest who died. We are also, naturally, supporting those guests and the guide involved in this distressing incident."

Mr Vincent added the vehicle had stopped because "sadly in this instance the terrain and vegetation was such that the guide's route became blocked and he could not move the vehicle out of harm's way quickly enough".
