PARIS, France - French national police say two people have been killed and about a dozen wounded in a shooting and hostage-taking in a supermarket in southern France.

A spokesman with the national police service told The Associated Press the attacker was still in the supermarket in the town of Trebes, but it was unclear if there were people still inside with him.
   
The spokesman said a police operation to apprehend the assailant is still underway. The spokesman was not authorized to be publicly named.

The reason for the shooting and hostage-taking is unclear, as is the identity of the attacker.

French Prime Minister Edouard Philippe says all information suggests that the shooting inside a supermarket in southern France and the earlier shooting of a police officer "seems to be a terrorist act".

Philippe says the hostage situation is ongoing Friday inside the Super-U supermarket in the small town of Trebes.
