Police have arrested a man in Grenoble after a group of soldiers were nearly hit by a vehicle while jogging near their barracks in south-eastern France.
A source close to the investigation said: "A person tried to run down two soldiers from the 93rd Mountain Artillery Regiment in Varces, for unknown reasons".
"There were a good 10 of them jogging outside their barracks".
No injuries have been reported and the motives of the attempted attack are unclear.
Isere officials called it an "odious act" and said it would be looked into by prosecutors in nearby Grenoble.
A man shouted death threats from his auto window at French soldiers out for a morning jog in the French Alps, then tried and failed to run several of them over, French officials said Thursday.
Macron decried the "barbaric" views that fueled Knoll's killing as well as the extremist who killed four people in a rampage in southern France.

The attacker wounded four other people, including the driver of the hijacked auto and a policeman shot while out jogging. Although police managed to get Lakdim to let other shoppers leave, he kept one woman with him as a human shield.
Radouane Lakdim, 25, began his killing spree when he stole a vehicle in the medieval town of Carcassonne, shooting the driver dead.
Radouane Lakdim, a Moroccan-born French national, had started his shooting spree by firing at a group of policemen returning from a morning jog in Carcassonne, injuring one of them.
The incident, feared to be another Islamist attack, came as ministers attended the funerals in southern France of a butcher, a wine-maker and supermarket shopper shot dead by a terrorist last week.
Francois Molins, who is heading up the investigation, said the attacker, Redouane Lakdim, 25, was known to security services for his links to radical Islam. It was then when Lt Col Arnaud Beltrame swapped himself for the hostage and was killed.
Last week, a man shouted "Allahu Akbar" as he stormed a supermarket in Trebe taking hostages before security forces stormed the building and he was killed.
Speaking Tuesday to the Associated Press, Daniel Knoll said, "My mother had a thirst for knowledge and meeting new people and talking to them, and that's what killed her".
