A car has struck a group of soldiers in a Paris suburb, injuring six, two seriously, police say.
Police sources say a man has been shot and arrested after they intercepted the car on a motorway north of the capital.
The soldiers were injured outside a barracks in the north-western suburb of Levallois-Perret on Wednesday morning.
The Paris prosecutor said the attack was "attempted killings... in relation to a terrorist undertaking"; anti-terror police are investigating.
France has been under a state of emergency since November 2015.
On 13 November, 130 people were killed in a night of carnage in Paris, and more than 100 have been killed in jihadist attacks since.
They include a string of assaults on the heavily armed security forces who now dot the streets of the capital - the last only four days ago.
Wednesday's attack at about 08:15 local time (06:15 GMT) took place outside a military barracks on the Place de Verdun in Levallois-Perret, the local mayor, Patrick Balkany, told BFMTV.
He said he had no doubt that the "disgusting" act was deliberate.
Car 'lay in wait'
He said a vehicle had been waiting in the road for the soldiers to emerge as they came on duty.
"It was a BMW which accelerated very quickly the moment they came out."
A resident in a nearby block of flats, Jean-Claude Veillant, told reporters he saw part of the attack.
"I heard a loud noise, the sound of scraping metal. 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.
The injured soldiers are being treated at the Percy military hospital in Clamart, but their precise condition has not been made public.
