A large search operation involving elite forces and helicopters is under way in France's southern Dordogne region after a man reportedly shot at police officers, France Info says.
There were no reports of casualties.
"The man, a former member of the army, is armed and on the run as we speak. A police operation is taking place to avoid things getting out of control," the prefect of Dordogne, Frederic Perissat, told BFM television on Sunday.
The Dordogne prefecture on Twitter urged inhabitants of Le Lardin-Saint-Lazare to stay at home until further notice.
