The fire broke out in a forest near the settlement of Shoresh on Tuesday. Eight firefighting planes and a helicopter were rushed to the scene, the fire and rescue services said.
Local residents have been evacuated and Highway 1, which connects Jerusalem and Tel Aviv, was blocked from Sha’ar Hagai interchange heading east, according to police.
The wildfire is approaching a nearby gas station and planes are now spraying fire retardants to prevent the flames from getting too close.
