Israeli police raided the plaza outside Jerusalem‘s al-Aqsa Mosque on Sunday in what they said was a bid to head off Palestinian attempts to disrupt visits by Jews and foreign tourists on the eve of the Jewish New Year.

Police used tear gas and threw stun grenades towards Palestinian youths, who barricaded themselves inside the mosque and hurled rocks and flares, a Reuters witness said. Israeli Public Security Minister Gilad Erdan, in a statement, claimed the Palestinian youngsters also had pipe bombs.

There was no sign that these had been detonated. No serious injuries were reported and the compound, revered by Muslims as the Noble Sanctuary and by Jews as the Temple Mount, was opened to visitors after the violence subsided, police said.
