A meeting of ministers will discuss a series of "lone wolf" attacks in France over the past three days. The latest, in the western city of Nantes, left 10 people injured.
French cities remain on heightened alert following a third “lone wolf’ attack, this time in the western city of Nantes.
Ten people were injured – five seriously – when a man ploughed his van into a crowded Christmas market.
Police say one of the victims is in a critical state.
President Francois Hollande has called an urgent meeting of ministers on Tuesday to discuss the three attacks.
The incident in Nantes followed a similar charge by a man in a vehicle in Dijon on Sunday which left 13 people hurt..
And on Saturday, a man was shot after he stabbed and wounded three policemen in central France.
In the Nantes attack, the driver went on to stab himself several times with a knife.
France’s interior ministry says it’s too early to determine the man’s motives and has called for calm and vigilance.
