A fire broke out on the northern slopes of the Yitzhar community in Samaria on Sunday afternoon.
Fire crews have been called to the scene working to extinguish the fire.
A fire department official told Arutz Sheva that there are suspicions the fire was intentional.
Last week, a forest fire burned over 1,500 dunams (370.7 acres) in the Jerusalem hills.
Gas canisters found in the debris also suggested arson, fire authorities said, after a similar fire broke out near the community of Even Sapir. Tens of homes were decimated in the fire.
