The soldiers targeted in Wednesday's incident were part of Operation Sentinel - a nationwide security operation aimed at "protecting against and dissuading" attacks on French soil. The driver is on the run.
A man has been shot and arrested in relation to Wednesday morning's assault when anti-terror soldiers in the northwestern suburbs of Paris were rammed into by a auto, leaving six injured. Police have closed off the roads.
Quoting unnamed police officials, however, the AP said a man was arrested at one stop. "Shortly after, I saw one of the badly wounded lying in front of the Vigipirate [army patrol] vehicle and another one behind it receiving treatment", he said.
Six of a dozen or so troops were injured in this morning's attack - three of them seriously - in the Levallois-Perret suburb of the city.
Three of the soldiers hit in the morning attack were slightly injured, while three were more seriously hurt, but their lives weren't in danger, according to the Defense Ministry.
Earlier, French Interior Minister Gerard Collomb said the attack was a "deliberate" act carried out by a "man on his own".
The wave of attacks in France has had a serious impact on tourism in the world's top tourist destination, but the industry has begun to recover as incidents have become more widespread and generally less deadly. Other soldiers ran after a speeding vehicle, shouting "After him!"
The Paris Police Authority announced Wednesday that police units have launched an operation in the area to find the auto that attacked the soldiers on route.
French government spokesman Christophe Castaner said the Paris prosecutor's office has opened a counterterrorism investigation.
"The vehicle accelerated towards the soldiers for five meters in order to hit them", he told reporters.
France has been under a state of emergency for nearly two years and has seen a string of attacks on security forces.
In April a policeman was shot dead by a man on the Champs-Elysées, who was later shot dead himself.
