Suspected IS gunman takes hostages in France supermarket
The attack took place in the town of Trebes. Shortly beforehand, an armed man shot and injured a police officer in the city of Carcassonne, about 15 minutes by car from Trebes. It was not clear whether the two incidents were linked.
French prosecutors said they are treating the hostage-taking at the Super U shop as a terror incident.
Police said at least two of eight people held are feared to be dead.
Since 2015, more than 239 people have been killed in France by militants, according to an AFP count.
