The other two occupants, the pair’s children, were left with serious injuries, ER24 spokesperson Werner Vermaak, said.

Vermaak said that, shortly before 6:00, paramedics arrived at the scene and found two overturned vehicles.

Vermaak said all the occupants had been ejected from the vehicle.

The two children were found with serious injuries and were treated and stabilised on the scene before they were rushed to a nearby hospital for further treatment.

The driver of the other car sustained minor injuries and later declined to be transported to hospital.

Vermaak said authorities were investigating the exact cause of the accident.
