Princess Diana died on August 31, 1997. She was only 36 years old when she was involved in an automobile accident in the Alma Tunnel in France.
She was taken to hospital in the early hours of Sunday morning where surgeons tried for two hours to save her life but she died at 0300 BST.
Dodi Al Fayed and the vehicle's driver were also killed in the collision in a tunnel under the Place de l'Alma in the centre of the city.
The princess' Mercedes car was apparently being pursued at high speed by photographers on motorbikes when it hit a pillar and smashed into a wall. Read more at BBC News.
