Residents of the Golan Heights in the north and the Dimona, Eilat and Nevatim areas in the south should stay near bomb shelters until further notice, the Israel Defense Forces said early Sunday.
The warning came as Iran launched its long-awaited response to the killing of several IRGC officers in Syria.
The Islamic Republic dispatched dozens of unmanned aerial vehicles from its territory towards Israel on Saturday night.
Two security sources in Iraq told Reuters that dozens of UAVs had been spotted flying from Iran towards Israel over Iraqi airspace.
An Israeli defense official told Army Radio that more than 100 drones had already been intercepted outside of Israeli airspace. The official said the UAVs were shot down by the United States and the United Kingdom.
