Military Police investigators arrested an Israeli soldier on Monday, following suspicions that he had leaked Israel Defense Forces operations in the West Bank to Jewish settlers.
The soldier, a married man and father of two children, served in the Samaria Brigade's rabbinate and has yet to be informed of the specific charges against him.
Military Police officials have also indicated that the man had been a known propagator of the "The King's Torah," a book written by the head of Yitzhar's Od Yosef Chai Yeshiva, which spells out the circumstances under which it is admissible to kill Gentiles who threaten Israel.
Tensions between the military and extremist settlers have been on the rise recently, following the demolition of three illegal homes in the West Bank outpost of Migron last month.
Following that incident, Israeli settlers vandalized an IDF post in the Samaria region in a so-called "price tag" attack.
IDF officials called the incident grave and unprecedented, as it marks the first time settlers had carried out a planned act of vandalism against army equipment.
The Yesha Council, which represents West Bank settlers, strongly condemned the act and called on the perpetrators to turn themselves in.
