From the Jerusalem Post:

Fifteen policemen were lightly wounded in their attempt to restore order on the Temple Mount after Arab youths emerging from Friday prayers started hurling rocks down onto those worshiping at the Western Wall. Having restored calm with the use of stun grenades, police left the Temple Mount compound in cooperation with the waqf to allow older worshipers to leave. […] The repeated clashes in Jerusalem follow Prime Minister Binyamin Netanyahu’s announcement incorporating the Cave of the Patriarch’s in Hebron and Rachel’s Tomb in Bethlehem onto Israel’s list of national heritage sites.

The clashes later calmed when adult Muslim worshippers dispersed the young stone throwers.
