Toulouse shootings: 'A sense of anxiety across France'

One of the biggest manhunts in recent French history is under way after four people were shot dead at a Jewish school in Toulouse.

Police have linked the attack to two shootings last week in which three soldiers of North African descent died.

The BBC's Christian Fraser in Toulouse says that police are investigating links to the far right and that there is a "sense of anxiety" across France while the killer remains at large.
