French police have arrested the main suspect behind an attack on soldiers in a suburb of the capital, Paris, the French prime minister confimed on Wednesday. At least six French soldiers were injured after they were hit by a vehicle in the northwestern Paris suburb of Levallois-Perret earier in the day, according to the city's police authority. A Reuters witness at the scene saw a BMW car, the model used in the attack, with several bullet holes in it. Ambulances surrounded the vehicle. One policeman was wounded by a stray bullet in the operation, which took place on the A16 motorway near Marquise, close to the ports of Boulogne-Sur-Mer and Calais. Gerard Collomb, the French interior minister, said that the incident was a "deliberate act". "[The car] was driving slowly and then, about five metres from the soldiers, the car accelerated and hit the soldiers," he said. "It is now the sixth time that military forces from Operation Sentinelle are the target (of attacks) since 1 January 2015." Al Jazeera's Natacha Butler, reporting from Paris, said that police stopped a car driving up the motorway that links Paris to the northern coast. "We believe that the suspect looked like he was going to reach for a weapon when the police opened fire," she said. "The suspect was shot several times but in fact we now understand that the suspect was not armed."
