PARIS — A usually quiet Paris suburb became the scene of a terrorist attack early on Wednesday, when a driver plowed his vehicle into a military patrol as the soldiers were walking to their vehicles, injuring six of them.

It was the sixth attack on French military forces since 2015 and added to the long string of attacks on uniformed security forces, Gérard Collomb, France’s interior minister, said in brief comments after the attack, underscoring the extent to which uniformed officers appear to be a focus for terrorists.

“We know this was a deliberate act,” said Mr. Collomb, describing how the car had approached the military patrol slowly, but then sped up, striking the soldiers.

By early afternoon, after a setting up checkpoints on the main roads leading out of Paris and a chase on a highway leading north, police officers in the Pas-de-Calais department captured a man driving the car that was used in the attack, which had been identified through surveillance footage. Later, President Emmanuel Macron, in Twitter messages supporting the security forces, said that the arrested man was the “author of the attack.”
