A man has shot himself dead with a sawn-off shotgun in the corridor of a nursery school in front of a dozen children, according to reports.
French newspaper, Le Parisien, say the 51-year-old man did not work at the school but lived locally.
The man is alleged to have been turned away from the building before returning with the gun shortly before midday on Thursday.

Radio reports say he threw newspaper articles on the floor before shooting himself.
The school is a private Catholic institution around a ten minute walk from the Eiffel Tower.
The school has been cordoned off and the children are being psychologically evaluated, reports the BBC.
