According to the Hospital of Cao Bang, four victims died on the spot and one died as he was admitted to the hospital.
There are two victims who are in a critical state and the two others whose entire legs must be cut off.
Witnesses said before the tragic accident happened, another accident occurred at the same place.
A truck from Hanoi plunged into the abyss and the driver was trapped inside the car. A group of passers-by stopped to watch and rescue the victim when suddenly a container truck ran very fast from the peak of the pass.
Seeing a crowd of people and vehicles on the road, the container driver jammed on the brake. The truck was thrown across the road and scanned the crowd to the abyss.
Those who witnessed the accident said there are several people who escaped from death by initiatively jumping down to the abyss.
Victims have not been identified yet.
