At least nine people died when a passenger coach collided heads on with a truck after having a flat tire in Thanh Hoa Province Saturday.
The coach was carrying relatives, including the parents, the uncle, and the cousin of the bride who were among the dead, to a wedding party from Nghe An to Hanoi. The wedding was scheduled on Sunday.
Initial police reports said the coach was driving fast when it tire went off, causing the vehicle to turn to the opposite direction and hit the truck in the afternoon.
Six people died on the spot, and three others succumbed to injuries on the way to hospital. Five others are in critical condition.
Initial police investigations showed that the brake of the coach had failed before it crashed into the truck.
