The Shin Bet says they have arrested a number of Jewish suspects in connection with the stabbing of an Arab man in Jerusalem last week.
The victim was seriously wounded in the May 13 attack.
The Shin Bet defines the stabbing as having a nationalist motive.
A restraining order is imposed on the identities of the suspects and details of the investigation.
Tensions between Israel’s Jewish and Arab communities had spiraled in recent days, with multiple violent incidents — at times deadly — as police appeared unequipped to handle the most serious internal unrest to grip the country in years.
