UPDATE 1-Armed teenager releases four hostages in southern France -police source

A teenager released four women after holding them hostage in a newsagent's store in Toulouse, southwestern France, on Tuesday, a police source said.

The 17-year-old, who was arrested at a yellow vest protest in December, had made no demands before releasing the women, the source said. He fired at least one shot over the heads of police and had demanded a negotiator, the source said, adding that the incident did not appear to be terrorism-related.

The gunman had not yet surrendered to authorities. Police and set up a 300-metre (330-yard) security cordon around the store in the city's Blagnac suburb and told neighbours to stay indoors.
