French counterterrorism prosecutors are taking charge of the investigation into the shooting of a police officer in southern France that has led to an apparent hostage-taking at a supermarket.

The Paris prosecutor's office said counterterrorism investigators are taking over the probe into the ongoing incident Friday in the town of Trebes, but did not provide details on why.

There are unconfirmed media reports that the assailant claimed connections to the Islamic State group.

Interior Minister spokesman Frederic Delanouvelle told The Associated Press that there is one suspect and police are trying to subdue him. He provided no details of how many people were inside the supermarket or were believed held hostage.
