Serial killer fears after Jewish school shooting

France was gripped by fears of a serial killer on the loose after a gunman opened fire at a Jewish school, killing a teacher, his two sons and another child.

It was the third such deadly attack in a week by a man on a motorbike.

The children, aged three, six and 10, and the 30-year-old religious education teacher, who was also a rabbi, were mowed down as they arrived for class at the Ozar Hatorah school in Toulouse, officials said.
