A terrifying video has emerged showing students hiding in a classroom and running for their lives as a gunman picked off victims during a shooting massacre at an Austrian school.
The chilling video circulating online shows the moment gunshots rang out around the BORG Dreierschuetzengasse high school campus in the city of Graz as terrified pupils could be seen hiding in their classroom.
In a separate clip, terror-stricken pupils are seen running down a corridor and a flight of stairs as they are escorted out of the building by heavily armed cops.
Two schoolgirls are shown clinging onto each other as they attempt to escape the school building.
Another disturbing video shows wounded bodies lined up on stretchers while dozens of paramedics tend to them. Some are covered by white sheets.
