The circumstance of the incident were not immediately clear. The shooting took place two days after a shooting in the city of Hadera that left two police officers dead, and a week after a stabbing in the southern city of Beersheba in which four people were killed.

The attacks have raised concerns that there could be further violence.

Police said Tuesday's shooting took place at two locations, apparently by a gunman riding a motorcycle.

The militant Islamic State group claimed responsibility for both attacks in the past week, in which the assailants were killed.
