At least one person has been killed and 10 others injured after gunshots were fired in the center of the northeastern French city of Strasbourg on Tuesday evening, the national police spokesman told CNN.
He also confirmed that there was only one shooter, who remains at large.
Live images from the scene indicate the incident took place near the Christmas market in the center of the city and there is a large police presence.
The interior ministry said in a tweet that there was an "incident" in Strasbourg and urged the public to stay indoors.
