JERUSALEM (AP) — Israeli police say vandals have torched two vehicles in an Arab neighborhood of Jerusalem in what appears to be an attack by Jewish extremists.

Police spokesman Micky Rosenfeld says the words “price tag” were found sprayed on a wall near the cars in Sheikh Jarrah on Friday. The phrase is usually used by Jewish extremists to protest what they perceive as the Israeli government’s pro-Palestinian policies, and to let Palestinians know who attacked them.

Vandals have targeted mosques, churches, dovish Israeli groups and even Israeli military bases with “price tag” graffiti over the years. In recent weeks, there has been a steady stream of such incidents, including an Arab Christian graveyard vandalized Thursday and a Jerusalem church defaced two weeks ago.

Rosenfeld says police are searching for the perpetrators.
