>> A heavily armed student opening fire at a high school in southeastern France on Thursday. Three people injured in the town of Grasse including the headmaster. Five are being treated for shock. The attack carried out after the 17-year-old had watched American style mass shooting videos, according to the Interior Ministry.
> I was in a classroom where everyone jumped out through the window and then we started climbing fences, the parking.
The individual was not known to the police who say the incident does not appear to be linked to terrorism. Witnesses described a scene of panic as the gunman entered the canteen with students rushing to hide under tables or sprinting for the exit.>>
I helped those I could to climb up. There were some girls who weren't able to climb so we carried them. Then we all left running. The police took us into their care and said to stay with them.>> Checks are underway to establish whether there was a second assailant.
Local emergency services used Twitter to advise residents to stay at home. The government launched a mobile telephone application warning of a terrorist attack, although this is now automatic for any such incidents. France is on high alert following the deaths of more than 230 people by militant attackers in the past two years.
With the presidential election less than six weeks away, this incident likely to further stimulate debate on security and terrorism.
