There has been a serious accident involving several heavy motor vehicles and at least one light motor vehicle on the N2 in Hluhluwe, about 40km from Lake St Lucia, in KwaZulu-Natal.
All vehicles, including a tanker, are currently alight and the flames have spread to the nearby bush.
Emergency services workers and firefighters are currently on the scene, says KwaZulu-Natal emergency services spokesperson Robert McKenzie.
"Firefighters are trying to contain the blaze which is burning out of control. It has also set the adjacent bush alight," he says.
