A gunman has shot dead a teacher and three children at a Jewish school in the French city of Toulouse.
The attacker fled on a scooter, in similar style to the killer of three soldiers in two separate incidents in the same part of France last week.
Police say the same .45 calibre gun was used in all three attacks.
Journalist Chris Bockman, reporting from Toulouse, said "nobody seems to understand how this man got away with it three times in a row".
