The Middle East diplomatic quartet expressed concern on Saturday about escalating violence in Jerusalem and called on all sides to “demonstrate maximum restraint.”

The Quartet comprises the United States, Russia, the European Union and the United Nations.

The envoys “strongly condemn acts of terror, express their regret for all loss of innocent life caused by the violence, and hope for a speedy recovery to the wounded,” the Quartet said in a joint statement.

“The Quartet Envoys call on all to demonstrate maximum restraint, refrain from provocative actions and work towards de-escalating the situation,” it added.

Two Palestinians died in clashes with Israeli forces on Saturday as the army moved in to seal off an attacker's home, following violence over security measures at an ultra-sensitive holy site.

On Friday, a 19-year-old Palestinian killed three Israeli settlers in the occupied West Bank and three Palestinians died in clashes with Israeli forces.
