Worshippers were performing the night prayer when police intervened at one of the mosque gates in the latest violence since new security measures were implemented this month by Israeli authorities at the holy site.
Anger has spilled across the West Bank since Israel shut East Jerusalem’s Al-Aqsa Mosque following a deadly shootout July 14. The site is venerated by Muslims and Jews, who call it the Temple Mount.
The mosque was reopened after two days, with Israel installing metal detectors and cameras at its gates.
Three Palestinians were killed Friday in protests against the measures around the holy site. Three Israelis were also killed in an attack in a settlement in the West Bank.
Israel refused to remove the detectors, claiming the security measures were similar to procedures taken at other holy sites around the world.
But facing international criticism and pressure, Israel's security cabinet decided late Monday to remove the metal detectors. A statement released after the meeting said a new surveillance system using "smart checks" based on advanced technology would be put in place.
Jerusalem is sacred Muslims, Jews and Christians -- and the Al-Aqsa Mosque is the Islamic world's third holiest site behind the cities of Mecca and Medina.
