TOULOUSE, France (AP) — A motorcycle gunman opened fire Monday in front of a Jewish school in the French city of Toulouse, killing a rabbi, his two small sons and one other child, the prosecutor's office said.

It was at least the third motorcycle killing in France in a week, shocking the country and prompting strong emotions and high-level discussions in Israel. French prosecutors were studying possible terrorist links, but the motive for Monday's attack was unclear.
