Former Israeli spy chief: Jews facing 'wave of terror' worldwide

A former head of Israel's Mossad spy agency says a shooting attack on a Jewish school in France is part of a "wave of terror" being directed against Jews and Israelis worldwide.

Danny Yatom spoke to Israel Radio after a gunman opened fire at a school Monday in the French city of Toulouse, killing a rabbi, his two sons and another child.

Yatom says he believes Iran or its Lebanese proxy Hezbollah is likely behind the attack, but did not elaborate. He says assailants prefer Jewish civilian targets because they are easier to hit than Israeli ones.

It was not clear who carried out Monday's attack.

Israel views Iran as an existential threat because of its nuclear program, support for militant groups and calls for the Jewish state's destruction.
