The town hall places the sequence of events at the group's arrival, then the fire at the two gates, before the projectiles that injured the principal. No other toll is specified at this stage.
The Bordeaux education authority, for its part, said that a complaint will be filed. This step is intended to bring before the courts the facts observed outside the high school.
A high school principal was struck in the head by a projectile in Bègles, near Bordeaux, after a group of hooded individuals burst in front of the school.
The episode targets both the high school's entrances and its head. The burning of the gates and the throwing of projectiles turned the surroundings of the school into a scene of violence.
One of these projectiles struck the principal in the head. The head of the school had to go to the hospital, the town hall says.
The education authority, for its part, confirms the intention to file a complaint, with no further public details on the principal's identity or the extent of his injuries.
According to the Bègles town hall, about thirty people with their faces concealed arrived by tram. They set fire to the two gates of the high school, then threw projectiles.
