French police are searching for a driver who ploughed into soldiers on patrol outside Paris on Wednesday, injuring six, two of them seriously.

The car targeted members of Opération Sentinelle, which form part of France’s ongoing state of emergency following the Paris attacks in November 2015.

The officers were standing by their vehicle at about 6am GMT at Place de Verdun not far from the town hall in Levallois-Perret.

"Police intervention is underway. Search underway for vehicle," the Paris police department said in a tweet.

The two seriously injured soldiers have been taken to the Percy military hospital at Clamart, near the French capital. None of the injuries are thought to be life-threatening.

Patrick Balkany, the mayor of Levallois-Perret, told BFMTV that a BMW parked nearby appeared to have been waiting for the soldiers to leave their barracks.

He described the attack as a “deliberate aggression”.

“It’s without doubt a deliberate act … This vehicle was waiting for them,” Balkany said. “The BMW accelerated very quickly the moment they came out. This happened in the middle of the town. It happened very quickly.”
