The occupants of the truck sustained gunshot wounds and were taken to hospital for medical attention," Zwane said.ER24 spokesperson Russel Meiring said their paramedics, along with other services, arrived on the scene to find the truck lying on its side on the margin of the road."Two men were found lying outside the vehicle while a third was found further up the road.
