Judea and Samaria Police received a report from the IDF about a mosque in Kutzra that had caught fire, apparently after burning tires were thrown into the building.
Police added that the mosque was not in use, and did not have holy books in it.
Vandals also sprayed the messages "Social justice for Ali Ein and Migron" on the walls.
Police officers entered the mosque to retrieve forensic findings. An investigation has been launched.
